AlcoSense Excel 
Fuel Cell Breathalyser

At a glance:

  • 64mm2 Fuel Cell Sensor – smaller version of Police sensor
  • Almost twice as accurate as award winning AlcoSense Elite
  • 48mm Full Colour TFT Screen
  • Works with any drink drive limit in the world
  • Re-calibration alert
  • Award-winning housing design

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.

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 was consistent in both tests when compared to the calibrated alcometer [Lion 500 Police Breathalyser]. That's quite impressive… In the few weeks I've had the unit I've had no issues with testing, the unit has consistently produced a reading that matches what I expected given the drinks consumed.

It's compact, easy to use and reliable. If you're in the market for a breathalyser then you can't go wrong with this one.”

Good product & good company to deal with.

by Steve SPM on 21/12/2020

I have used the original Alcosense Elite for +/- 5 years and always found the results to be consistent and reliable. I sent the unit for calibration, to find that it was not holding calibration. I was called by Alcosense and offered, not only a trade-in for my old unit but they also took off the money I had paid for the calibration.
Excellent customer service, excellent company to deal wit.
The Excel model is easy to set-up out the box, setting the BAC limit to Scotland's strict limits - downloaded the software and checked for updates, although the latest Firmware was already installed. I would not hesitate to recommend the Excel unit & Alcosense as a company.
