AlcoSense Excel

Designed from the ground up by AlcoSense in the UK, the Excel utilises the award winning chassis of the AlcoSense Pro and Ultra to bring an entry level fuel cell breathalyser with outstanding accuracy and functionality to the sub £100 price point.

Fuel Cell Accuracy

Fuel Cell Accuracy

The Excel uses a 64mm² version of exactly the same 200mm² Fuel Cell sensor used in several UK, US & European Police Breathalyzers. Many brands claim they feature "Police Sensors" or similar, simply because they use a fuel cell sensor. But not all fuel cells are the same... The Excel’s sensor is identical to the law enforcement version, just smaller, giving the Excel unrivalled accuracy at this price point.


Breath Volume Sensing with Temperature Compensation

The most accurate way to measure breath alcohol is to measure the deep lung air, to get to this air the user must to blow out 1 litre of air before a reading is taken. If the reading is taken too early the breathalyser can give low or inconsistent readings. Most rival products at this price point rely on using a timer to estimate when 1 litre has passed but users blow at different pressures meaning the actual volume when the measurement is taken can vary wildly leading to the sample being taken at the incorrect time and an inaccurate reading being shown to the user.

The AlcoSense Excel senses the volume of breath exhaled during the test and takes a reading when 1 litre of air has been exhaled, ensuring the most accurate and consistent sample is always taken. To improve accuracy even further, readings are fine-tuned according to temperature – so whether we’re in a heat wave or the biggest snowfall for 30 years the Excel will compensate to ensure the best accuracy possible. 


Eliminating Under-Reading

Every breathalyzer has an accuracy tolerance of +/- X.XX of the reading – the smaller the number the more accurate the breathalyzer claims to be but this means that the reading could be higher or lower than the true reading by this amount. The AlcoSense Excel has some clever software to stop under-reading – i.e. instead of having a tolerance of +/-0.10‰BAC, the AlcoSense Excel’s tolerance is +0.15‰BAC, -0.00‰BAC. This means the Excel will read a little on the safe side, not too low and more than twice as accurate as the award-winning AlcoSense Elite.

 AlcoSense Excel

Any Limit in the World – Literally

Using the simple menu system the AlcoSense Excel can be set to any limit, anywhere in the world. You can adjust the units of measure between mg/L (breath alcohol) and ‰BAC (blood alcohol) readings, the drink drive limit and blood breath ratio. If you’re travelling abroad all you need to do is set the three parameters according to the table in the user manual. Ideal for cross border or even cross continent travel.

Adjustable Drink Drive Limit

If you’re looking for something even easier, consider the AlcoSense Pro and Ultra which come with a pre-loaded database of over 40 limits around the world. Just choose your country in the menu and at the click of a button it will set every up for you according to the local legislation.


Award Winning Design

The AlcoSense uses the same housing as the AlcoSense Pro and Ultra – winners of the 2016 Red Dot International Product Design Award. Previous winners include Apple, BMW, LG, Porsche Design, Lenovo, Bose and Dell, and now AlcoSense!

2106 Red Dot  Design Award Winner 

Detailed, Easy to Understand Results

AlcoSense Excel features a full colour 1.8 inch (48mm) TFT screen which gives clear and detailed readings of your alcohol level in your choice of breath (mg/L) or blood (‰BAC) readings. If you’re close to or over your chosen limit the Excel will alert you not to drive.

Low or Zero Alcohol Alcohol present but under the limit
Zero or trace alcohol    Alcohol present but

Close to or over the limit

Memory Recall

The Excel stores your last 24 readings in its memory for easy review at a later stage. If you require a larger memory, or with date and time stamp please consider the AlcoSense Pro and Ultra.

Easy to Use Graphical Interface

The Excel’s software is built upon the same easy to use platform as the award winning Pro and Ultra. The Excel gives you prompts and instructions on screen and a simple and easy to use menu system.

Backlit “Twin” Blow Tube Receptor

The Excel features a backlit blow tube receptor so it’s easy to put a blow tube even in low light. The Excel works with both the “Pro” mouthpieces which feature a one-way valve to eliminate contamination from previous tests for ultimate accuracy, or the “regular” blow tubes used by the AlcoSense Lite and Elite.

Re-Calibration Alert

Any breathalyzer requires re-calibration after a period of use, the AlcoSense Excel has an industry leading calibration period of 12 months from the first time you use it. To improve reliability and user friendliness AlcoSense Excel reminds you to recalibrate after 11 months of use. When calibration expires just post it to us and we will recalibrate it using Police spec Breath Alcohol Simulators and return it to you within 5 working days.

Temperature Alerts

If a breathalyzer is used outside its operating temperatures you can get erroneous readings due to temperature affecting the quality of the reaction inside the sensor. For your safety and protection AlcoSense Excel will alert you if the unit goes outside its operating range (note the operating temperature is the temperature of the unit, not the surrounding air temperature) of 5°C~40°C. This means that, unlike rival brands, the Pro will never let you perform a test when you could get an unreliable result.

Saturation Protection

Unlike rival brands, AlcoSense Excel also protects you from inaccuracy caused by “Sensor Saturation”. Sensor Saturation can affect any breathalyzer, including Police units and is caused when extremely high levels of alcohol are blown directly into the sensor. Normally this happens when a breath test is performed shortly after drinking when alcohol is still present in the mouth, the sensor can be overloaded, known as “saturation”. Readings taken after a saturation event can be unreliable until the sensor recovers. For your safety and protection, rather than allowing potentially unreliable readings to be shown, AlcoSense Excel will enter a protection mode which allows the sensor to recover before allowing further tests.

Quality & Reliability Assured

Quality Assured with ISO13485

The AlcoSense Excel is manufactured under ISO13485 conditions, the benchmark in medical device quality systems. After calibration, each unit is then tested 3 times for accuracy before leaving the factory meaning that the Excel is a device you can rely on.

“The AlcoSense Excel is [for] those who rely on their license for work or play, and who seek reliability and accuracy at an affordable price. We tested the accuracy of the AlcoSense Excel against a £13,000 evidential breathalyser used in Police stations and the readings were almost identical.”

It is extremely well engineered and easy to use

by Ian Clough on 22/03/2017

Just been using this for a few days. It replaces a previous cheaper model.It is extremely well engineered and easy to use. The display show you how hard to blow and hence I guess that this must improve accuracy.It is easy to set-up for different countries and is aware of the limits in each country.The only downside is that the blowing tube is separate which means that I need a case. My old unit had a fold out tube so I could just throw it in a suitcase when travelling. Good product, fast delivery.
Good service from a British provider. Dear

by David S on 09/03/2017

Good service and an upgrade to a more expensive model as they were having software problems with the one I had ordered. Easy to set up and easier to use. So far use has been limited but I can see no reason to think that it will not give good service.

by Amazon Customer on 03/03/2017

This is a great investment. I'm not the type to ever drink and drive but sometimes I can't be sure about the morning after but with this I can be confident that I'm not risking my licence.It's really easy to set up and use with great features and most importantly when compared to cheaper models its got the accuracy you need. Some of the cheaper models out there have a +/- tolerance that's as high as the legal limit!Buy cheap, buy twice.

An Invaluable piece of equipment for anyone who needs their driving licence!

by Mr. A. K. Butcher on 02/02/2017

Excellent product. I use this regularly at weekends the morning after I've been drinking. The device not only tells you your alcohol reading, but when you'll be sober enough to drive again! As I need my licence for my job, this is an invaluable piece of equipment!
Be smart, don't drink and driver at all

by Mr W. on 28/01/2017

I've tried a couple of the lower end BA meter and found them to be flakey and not even trustworthy enough to show a go/no-go level.In our family we all (four drivers) use a BA meter for the morning after, not to indicate how many more units we can get before we are dangerous.Be smart, don't drink and driver at all......Do use the Alcosense range to give you the 'all-clear' the morning after.

AlcoSense Excel,,simple,inexpensive and so effective.

A very impressive,easy to set up unit!!,i was given the Excel to review,totally free of charge,as i'm already an AlcoSense Elite user..I found the product simple to set up and set the parameter's..I would recommend this unit to anyone,,the cost far outweighs the cost of being inadvertently over the drink driving limit..that's peace of mind!
Very Impressed with this latest Breathalyser

by Amazon Customer on 16/01/2017

As I live in Scotland, I purchased an AlcoSense Elite a couple of years ago when the drink drive laws changed. As a professional driver and with the drink drive limit in Scotland being so low, I have always been impressed with the AlcoSense Elite, however when I read that the Excel had just won the Auto Express best buy for 2016, I decided it was time to upgrade to the latest model – So far I have not been disappointed!
Excel model

by M A WEBBER on 15/01/2017

Very prompt delivery. Setting up the product was achieved without difficulty and has been tested by myself and several friends. I believe this is a very sensible device to keep handy when entertaining at Home, or in the Car when going out for a celebration/meal.Sufficient Blow Tubes are provided together with the batteries required to operate the product.The only drawback, if that is a fair comment, is the suggestion that the product needs to be re-calibrated by AlcoSense every 12 months at a cost of around £25.00. No mention is made of the number of times the product could be used without calibration being necessary. That is something I will take up with the Company when the machine advises me, in 12 months time, that it needs to be re-calibrated.

After researching the market I chose this product as a result of its consistently being ranked the most accurate device available at an affordable price. I am not disappointed. It is straightforward to set-up and use, and its size is such that it takes up little room in my bag. The Alcosense customer service is excellent as they were out of stock of the model I ordered and sent me a superior product at no cost to me.
Quality, easy to use and reliable personal breathalyser

by Miguel on 10/01/2017

I upgraded from the Alcosense Elite. The device is a little larger than the previous model but still fits easily in a pocket (or the glove box). The Excel is easy to set up and to operate with clear on screen prompts to guide you (only afterwards did I think to look at the instructions booklet).Once set-up the device is simple to use with no need to delve into the settings unless you're travelling between different jurisdictions or just curious. If needed, the setting's menus are simple and straight forward to follow. The Excel powers up quickly (within 5 seconds) and does so silently (a nice feature compared to the whining noise of the Elite, which took about 15-20 seconds). Following a test the results are displayed with a large digital display (in the units of your choice BAC% or Mg/L) and a clear colour indication warning you not to drive as appropriate.The Excel comes boxed with 3 x AAA Batteries and four mouth pieces -although a pack of 25 at £10 is almost twice as much as the Elite "straws" they are much more robust and if limited to personal use can be washed and reused.Having read the Auto Express review (backed with a little science), and spent a little longer using the earlier Elite model, I am reassured that this is a quality product and one I am prepared to depend upon (the morning after) to protect my licence. Product was dispatched quickly and arrived within a few days.Disclosure: As an existing AlcoSense Elite user I received the Excel as a free upgrade in exchange for an honest product review.
Great product, easy to set up

by Finchy on 04/01/2017

Great product, easy to set up, easy to use. A must have for anyone considering a few drinks in the evening knowing they need to drive the next morning.
Really Quick and Easy to Use - No Brainer

by Mrs. Amanda R. Axel-berg on 27/12/2016

As I had previously purchased the AlcoSense Elite, I was offered a free upgrade unit of the AlcoSense Excel in exchange for an honest review of the Elite.This are my experiences of this unit, the information provided is accurate to the best of my knowledge at the time this review was written.Consult the user guide, manufacturer and your local laws for advise on alcohol limits and the driving law in your area.Do not drink and drive.PROS:- Easy to use (menu driven with three buttons)- Calibration before each use is very quick (takes around 10 seconds before it's ready to use, much quicker than others I've used)- High quality and easy to read screen (really impressed with this)- Very Good build quality (family member described it as looking like an Apple product)- Quick Response with Reading after test- You don't have to blow into unit for too long before it reads the result (Elite took quite a lot of time breathing into unit before it would analyse)- "Accurate" - Several concurrent tests produced the same or very similar results (also tested with a group of people)- Easy to know when not to drive - if within 20%-80% of drink drive limit goes amber, if within 20% of limit clear do not drive warning displayed- Unit powers on quickly- Unit can be updated via included USB Cable- Easy to change settings, if neededCONS:- The tester blow tubes can easily be lost (spares ARE included, however)- One result produced a wildly inaccurate result (the user had just had a drink before testing - AlcoSense clearly warn against doing this)After receiving an eMail from AlcoSense offering me a free upgrade, I sent off my existing unit and ordered I a replacement unit at no cost, which arrived promptly.N.B. I notice AlcoSense offer a discount on each of their models, if upgrading from a cheaper model (just send back your existing unit in exchange).The box includes the breathalyser, USB Cable, Batteries, Tubes for testing and the user manual.After opening the box and installing the batteries, I powered on the unit and was immediately impressed by how much better the screen is (high quality colour TFT Screen).The initial setup is very easy (and can be done without the manual!). You set the time/date and alcohol limit and unit type (will give you a country list for reference).To use it, you slide the top of unit up and insert a blow tube into the hole at the bottom.I tested the unit on a couple of occasions with both myself and my family over Christmas and everyone was impressed by the build quality and easy of use of the product.I also tested myself 3-4 times over 15 minutes to make sure the result was accurate and found the result initially returned the same result then slowly dropped.I would definitely recommend spending the extra money and going for this over the Elite, and would avoid cheap breathalysers!I've had bad experiences with cheap breathalysers in the past, but have been very satisfied with both the Elite and the Excel.Both units are small enough to fit into my glove box and storage draw in my car. I've kept both in the car and always use them the morning after to check I'm safe to drive.N.B. It's important that you don't test yourself for at least 45 minutes after your last drink as your alcohol level may continue to rise as your body will continue to absorb alcohol for some time after your last drink.It's also worth noting that if any alcohol gets onto the sensor it will give an invalid reason as the alcohol concentration is too high (and can damage the sensor).One family member blew a result of around 4% BAC, which was way higher than anyone else (who'd drunk more). He'd taken a drink just before blowing into it.However, after a minute or so, I tested myself again and found the result was the same as my previous result so it appeared not to have damaged or affected the unit adversely.It's better not to drive at all the same day and use a breathalyser for the morning after.You can get any of the Alcosense Breathalysers calibrated for about £20, so you know they're still accurate after a year.

by RH on 24/12/2016

First breathalyser I have owned. Very easy to use and seems like good quality. Tested the morning after a party and was over the limit, scary how easy you could lose your licence. Very happy with my purchase.

Highly Reliable and Accurate Breath Analyzer!

by AC on 20/12/2016

If you are reading this review, I am sure you are looking for a Breath Analyzer which is reliable, accurate and provides peace of Mind. ALCOSENSE make some great products in this area. Their products are not only good, but they have an EXCELLENT CUSTOMER SUPPORT and provide very quick replies to all inquiries.There are lot of breath analyzers in the market which are cheaper. These may or may not provide accurate results. DO YOU WANT TO USE A NON-RELIABLE BRAND AND RISK YOUR LIFE AS WELL AS LICENSE? I do not think so…. please do not buy something which cannot assure accurate results… as this nullifies the need to purchase a breath analyzer in the first place.The product from AlcoSense, looks great, has a nice screen, intuitive menu options and provides very accurate results. I recently bought and tested this myself and also my friends have used it. Everyone was really very impressed by this little device which provides assurance similar to Professional Grade Police breath analyzers.ALCOSENSE ALSO HAS NUMEROUS REVIEWS AND AWARDS FROM THE TOP REVIEW SITES WHICH AGAIN VALIDATES THEIR CLAIMS AND HELPS MAKE THE RIGHT CHOICE.Again, if you are looking for Breath Analyzers, invest and Get Alcosense Excel. And if you Budget affords get the Pro version. Take the Guess work out and Have a Safe and peaceful Drive. 10 Stars to Alcosense for their products!! HIGHLY RECOMMENDED and a MUST BUY!!

Never lose your Driving licence

by Riz F. on 18/12/2016

I owned the Elite Alcosense and was offered a free upgrade to Alcosense excel for an honest review.Arrived on time as promised. Well boxed and packaged. Compact and modern design. Measurements are L= 10cm, W=5cm, D=2.5cm but can carry in your pocket. It comes with batteries and five tubes. Setup takes less than 5 mins. If you read the clear instructions and follow as requested, you will not go wrong. Tried it after one drink followed by a coffee and 30 mins, came back with below limit as expected. Tried it on a friend after three drinks and it failed him. Clear colour readout and immediate result. A definite upgrade from the Alcosense elite.You carry this in your pocket or handbag. No guesswork required. I can drink and party without worry. Other plus points are that it can be setup for use in pretty much most countries in the world besides the UK.Well done Alcosense.

I received the AlcoSense Excel free of charge to review as an existing AlcoSense Elite user and I am really happy with it. The Excel is a big step up on the Elite, not only is it super easy to use but the higher accuracy of this model gives you piece of mind. I really like the display as you get a lot more information from it than what you got with the Elite. It's really quick and easy to perform a test, just what you want to check that you're safe to drive.
Excellent product. You know it makes sense !

by Amazon Customer on 15/12/2016

This is an excellent product. Not cheap but the accuracy determines the quality. I need my driving licence and the new alcohol limits here in Scotland have been lowered making drivers ultra cautious. I read the rigorous test results in Auto Car magazine and bought on the strength of that. Since then I have done a fair bit of testing out of curiosity to give myself a better understanding of BAC ( breath alcohol content) and the educative ,clear and instructive guide included helped greatly. The ability to easily change the various parameters for different countries is useful and simple. Why can't more products be this good. Honestly, I'm impressed. I am not an employee or shareholder in this company but will check and see if they are listed. I bought this breathalyser for the "morning after" especially this time of year( Christmas) but it has been useful in other circumstances too. We had to return to a restaurant as a friend had left his meds, after waiting the appropriate time , the breathalyser showed he was below the limit to drive and saved a costly taxi fare. It has a quality finish too, reminiscent of an apple product.

by Phil on 14/12/2016

Quick delivery of item. Was easy to set up and use and is very accurate with clear readouts and advice. A must to ensure you are OK to drive, especially the next morning after a night out. Can be quicky changed in the menu to use in many other countries with differing legal levels of alcohol in breath or blood.

by Bronco on 12/12/2016

The Alcosense Excel is a Breathalyser that is well packaged, easy to set up (around 3 mins) and intuitive to use. Size wise - it's slightly bigger than the Elite, I guess about the same size as 2 decks of playing cards stacked on top of each other or just a bit thicker than a pack of cigarettes (does anybody smoke anymore?) so it can easily fit in your pocket, handbag or car glovebox.I've been using this product and the Elite for just over a month now - it's Party Season and I can't afford to take any chances with either the safety of others or my livelihood which depends on me being able to drive. It's been surprising/sobering to see just how much alcohol is in your system - on a couple of nights I've returned home (via taxi of course) and felt "absolutely fine to drive", I tested myself and on one occasion I was at 0.85 BAC so definitely not good to drive and on the other occasion I was under 0.5 BAC so legally able to drive in the UK - I couldn't discern the difference at the times with how I was feeling. This produce is marketed more as a "morning after" tool and to that end I was surprised when going back to our friend's house to pick up our car how much was left in my system from the night before - 0.28 BAC which was a good 9hrs after my last drink (it was a good night).So my advice is, take the guesswork out - don't risk being over the limit and driving... get one of these today. My family have been hearing me rave/bore on about these and have all asked for one in their Christmas stocking - which I'm only too happy to oblige.Cheers!BPlease Note: I received the AlcoSense Excel at a small discount to review as an existing AlcoSense Elite user. I've decided to keep both and I can recommend both, they each have their separate price points - the differences as I see them are... Excel is: slight bigger; easier/quicker to set up (can be used straight out of the box whereas Elite requires you to activate the sensor with a small bit of alcohol); has a better display (colour); is slightly more expensive to service £25 compared to £20 (annual service recommended).
AlcoSense Inhaler tubes

The inhaler tubes don't seem to fit the machine very well
Save your licence

Upgraded to this having previously had the Elite.This model uses same tech as police.Very easy to set up and seems very accurate.Used after a party next morning also on some guests who had stayed over,after following instructions 4 out of 5 failed they were shocked but saved their licence.In comparison to losing you licence this is well worth the investment.BEWARE of cheap Chinese machines that are not accurate!
The Excel does it all

by Mr. J. G. Sutherland on 09/12/2016

Like many, I have upgraded from an Elite to the Excel and I am certainly not disappointed. Whilst it is a slightly larger unit, it is still compact in the using and transporting sense. A lovely piece of kit which certainly does the job with ease. The whole offer is superb - the packaging is great - the style and finish of the product is excellent and the instructions are so clear - a delight. It is really nice to come across a product and a company that deliver a great product and service. I assume, with great confidence, that the product does the job. It is a reassuring product. Thanks
Auto Express best buy 2016 review – spot on.

by RichmtBat on 07/12/2016

I bought the AlcoSense Excel after reading the Auto Express best buy 2016 review. It’s really simple to set up and use and from the tests I’ve carried out on myself, it appears to be very accurate.
I’m not disappointed at all

by Theo on 04/12/2016

I got this to replace an AlcoSense Elite I’ve had for many years. I went ahead and got it after seeing the Auto Express group test it won last week. I’m not disappointed at all! It’s a great bit of kit and a big leap from the Elite model I previously had.

Pros: The design is nice, screen easy to use and the alerts clear. The menu is easy to use and straight forward. I can’t test the accuracy scientifically but it seems exactly where I would expect it to be from experience and the readings are very consistent and repeatable, however, Auto Express tested the accuracy scientifically and it came out top so that’s good enough for me!

Cons: none yet!
The best product ever. Recommend.

Perfect breathalyzer for morning after. It is very accurately.
Peace of Mind

Accuracy, that's the big question.I've been looking for a Breathalyser for a while as I have been worried by the "Morning after" risk. I don't drive the day after if I have been out on a night where I have a lot to drink but hearing people quoted as saying "I felt fine but I was over the limit" was a concern, I wouldn't drive unless I felt fine but what is my actual Blood alcohol level? Looking at items on market, very few quote accuracy, this brand does and also offers a re-calibration service! So then it was cost. Having personal experience of Fuel Cells they are a recognised method of measurement, so this offered the best value for money for me. The item is quite chunky and solid and offers a PC connection for results.In this time of "You get what you pay for" this offered me the best balance of Cost vs Do you believe what it is telling you? This made sense.
Fantastic Product

by Dingo on 30/11/2016

This is a fantastic product.. as someone who drives for a living. The morning after always worried me. As I have to dine out with Clients a couple of times per week. Event if I only have 2-3 glasses of wine I never knew if I was legal to drive the next day.. now its a simple test and I can drive with confidence... would recommend this to everyone . I think everyone should own one...

Great bit of kit. Well built and easy to use
Excellent breathalyser with Police Breathalyser technology.

by abm on 24/11/2016

Really happy with this Breathalyser . The AlcoSense Excel was really easy to set up and use with clear display screen results. The fact that it uses the same technology used in many Police Breathalysers inspires me with confidence. It’s compact size makes it really easy to keep into the glove box in the car and I would recommend this for all drivers especially coming up to the Christmas drink drive period as it may save you your license.
Brilliant piece of kit to protect my driving license.

by Emma on 23/11/2016

I am absolutely delighted with the new Excel and it is easy to see as to the reason it has won the Auto Express Best Buy award. It was simple to set up with very clear instructions. I regularly drive early in the morning and therefore it is an absolute must to protect my license. Would definitely recommend.
