AlcoSense Pro Fuel Cell Breathalyser

Pro at a glance:

• 121mm² Fuel Cell Sensor – smaller version of Police sensor
• More than twice as accurate as award winning AlcoSense Elite
• Time until Sober & Retest alarm
• Selectable database of all drink drive limits worldwide
• Blow Coach making it extremely easy to use
• Winner – 2016 Red Dot Product Design Award

At its price point, the AlcoSense Pro is arguably the most advanced breathalyzer on the market. The culmination of 3 years of research and development, the AlcoSense Pro (and its bigger brother, the Ultra) take accuracy, features and ease of use to a new level.

Designed from the ground up by AlcoSense in the UK with Patented new features, the Pro packs the punch of a breathalyzer twice its price and brings near Police accuracy into the reach of the consumer.

Professional Accuracy

Pro by name, pro by nature. It uses a 121mm² professional Fuel Cell sensor, identical to its 200mm² big brother used in several UK, US & European Police Breathalyzers – and in the AlcoSense Ultra. This gives the Pro unrivalled accuracy at this price point and accuracy of almost twice the AlcoSense Elite.

Advanced Sampling System with Temperature Compensation

The AlcoSense Pro features an advanced sampling system to ensure that only deep lung air (the most accurate part of the breath) is measured. It uses advanced sensors to measure the blow pressure, flow rate and volume of breath exhaled and takes a reading when 1 litre of air has been exhaled, ensuring the most accurate sample is always taken. To improve accuracy even further, readings are fine-tuned according to temperature. These sensors also allow the Pro to get clever with BlowCoach™

BlowCoach™

Most issues while doing a breath test are caused by either blowing too hard, too soft or not for long enough, and with some products this can also cause inaccurate results. BlowCoach™ is a Patent Pending technology from AlcoSense which makes it simple to do the perfect test every time!

The Pro shows you real-time on screen feedback of how you’re blowing. All you need to do is keep the top pressure bar in the middle, and keep blowing until the bottom volume bar is full.

Blowing at too softly

Blowing correctly

Should you get it wrong, this is where the Pro gets really clever. Using it’s on board sensors the Pro diagnoses exactly why the test failed and gives you tailored tips so you can quickly get it right next time.

BlowCoach™ dramatically reduces the learning curve of using a breathalyzer and makes operation simple.

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. The AlcoSense Pro has some clever software to eliminate the downside – i.e. instead of having a tolerance of +/-0.1‰BAC, the AlcoSense Pro’s tolerance is +0.10‰BAC, -0.00‰BAC. This means the Pro will read a little on the safe side, not too low and more than twice as accurate as the award-winning AlcoSense Elite.

Any Limit in the World – Literally

At a click of button the AlcoSense Pro will work with any limit, anywhere in the world! Just select the country/region you’re driving in from the menu and using AlcoSense’s patent pending technology the Pro sets every up for you according to the local legislation. It sets the limit, unit of measure and blood breath conversion ratio to allow accurate readings in either blood alcohol or breath alcohol. Should a limit change the unit can be updated through a software download from our support section. Ideal for cross border or even cross continent travel.

If you want to set your own self-imposed limit, for example maybe half the drink drive limit, you can do that too! Just select “Limit” from the main menu to adjust it to the limit you desire.

Award Winning Product Design

The AlcoSense Pro and Ultra won the prestigious 2016 Red Dot Award for Product Design. The Red Dot Design Award is an international product design prize awarded by the Red Dot Design Museum in Essen, Germany. In 2016, a total of 5,216 products were assessed for the award by a jury of 41 independent design professionals. Past winners of the award include Apple in 2001, BMW in 2007, LG in 2008, Porsche Design in 2012, Lenovo in 2013, Bose in 2014 and Dell in 2015. You can find out more by clicking here.

From the ground up, the product design communicates the AlcoSense Pro's core values of simplicity and precision. 

Detailed, Easy to Understand Results

AlcoSense Pro 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 µg/100mL) or blood (%BAC or ‰BAC) readings. If you’re close to or over your chosen limit the Pro will alert you not to drive.

No alcohol

Up to 80% of the limit

Close to or over limit

Time Until Sober & Retest Alarm

AlcoSense Pro will even calculate how long it may take until you’ll be sober and show it with your results, see screen shots above and below. Want to have a reminder to re-test again later? No problem, just press the alarm icon and the Pro will alert you to retest again later.

Sober in time shown with results, press the bell icon to set a re-test reminder

Easily adjust when the timer will remind you to re-test

Memory Recall

The Pro will store 128 test results with both the date and time of the test.

Backlit “Twin” Blow Tube Receptor

The Pro features a backlit blow tube receptor so it’s easy to put a blow tube even in low light. The Pro 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 Pro has an industry leading calibration period of 12 months from the first time you use it. To improve reliability and user friendliness AlcoSense Pro 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 Pro 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 Pro 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 Pro will enter a protection mode which allows the sensor to recover before allowing further tests.

Quality & Reliability Assured

The AlcoSense Pro 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 Pro is a device you can rely on.

"The AlcoSense Pro and Ultra have been awarded the international distinction of the Red Dot Award for exceptional product design against competition from multinationals including, Dell, Lenovo, LG, Apple, Logitech and many more. A total of 5,214 products from 57 nations were assessed by a jury of 41 independent designers, design professors and specialist journalists to decide the winners of the 2016 Red Dot Product Design Award, with the AlcoSense Pro and Ultra breathalysers winning the “Red Dot Award: Product Design”.

Red Dot has been an internationally recognised design award since its inception in 1955 and is recognised as a quality label for excellent product design. Past prize-winners include Siemens in 1995, Apple in 2001, BMW in 2007, LG in 2008, Porsche in 2012, Lenovo in 2013, Bose in 2014; and Dell in 2015.

Designed in the UK, the AlcoSense Pro & Ultra are the culmination of 3 years R&D and reflects AlcoSense’s values of simplicity, functionality and precision. The result is a breathalyser with near Police level accuracy and several patented innovations which bring a level of performance & ease of use previously unseen in the industry.

The product’s external design also impressed the jury by reflecting these values in a refined the external form with precise split lines and slide action with hidden mechanism, invisible battery compartment and backlit mouthpiece hole for use in low light conditions."

The test involved using a machine to pump vapour from a solution of alcohol and water (using a human test subject introduces inconsistencies) into a Draeger police evidential breathalyser, which is used at police stations (they offer an industry-best ±0.03‰ BAC), and immediately after running the same test with the Pro.

The results: 

• Draeger Alcotest 9510: 0.312mg/l
• AlcoSense Pro: 0.32mg/l

The AlcoSense Pro got impressively close to the benchmark police evidential breathalyser. 

In addition, helpful features of the Pro include colour-coded results (red being over the limit), a backlit tube connector, the amusingly-named BlowCoach (shows in realtime whether you're blowing too soft or hard to get an accurate reading), and a handy Time Until Sober reading.

The Pro also works abroad as it includes a database of legal limits in various countries/regions — you simply tell it where you are and it'll do the rest.

the AlcoSense Pro appears to be a good investment for any law-abiding driver, especially during the Christmas party season, to make sure you're not caught out the morning after. The alternative could ruin your life.

10th February 2016

"The sleek Alcosense Pro is handy and simple to use, with a high-spec fuel-cell sensor that gives almost the same accuracy as police kit. The sensor has accounted for a 10 per cent tolerance, to prevent giving an under-reading. It also helps control breath flow, so you don’t breathe too hard, too softly or not long enough – all explained on the hi-res colour TFT screen. If you’re over the limit, it’ll advise how long to wait until you’re sober. EXACTLY when are you safe to drive again the morning after a night out drinking? There’s no real certainty, so investing in a personal breathalyser is one way to be sure."

"Alcosense Pro is a top-of-the-range model and offers reliable accurate readings, which could prove priceless... As far as breathalysers go, this is one of the best"

"Designed in the UK, both breathalysers offer levels of accuracy, reliability and consistency that we as consumers have not been able to access until now."

"The units have several excellent features. They are pre-loaded with all the different limits in every country, so if travelling in Europe, for instance, you wouldn’t be caught out by different levels when crossing borders. Also, they feature an ‘estimated time until sober’ with an alarm that alerts you to re-test again when it is likely you will be safe to drive. The AlcoSense Pro costs £129.99 (£149.99 from February 2016) and the Ultra is £249.99 – which isn’t cheap but considering the alternatives could be a bargain."

"An AlcoSense Pro breathalyser could be the smartest gift you buy this year. The Pro knows it is in Scotland, knows the limit and can even tell you when you can next drive. It uses a 121mm2 version of the 200mm2 “Fuel Cell” sensor used in several UK police forces. That sounds technical but this machine even gives you a lesson on how to give a breath sample properly with its BlowCoach mechanism. It doesn’t get any easier than that. — so there are no excuses for being over the limit."

"Just how accurate are home breathalyzers? We test one against a Police-spec unit.

We tested it [AlcoSense Pro] scientifically (not in the pub, honest) with some control alcohol measured to read just below the UK’s 35ml drink-drive limit. Tested on the sort of super-accurate unit the Police will use at the station for your conviction, we found our test unit [the AlcoSense Pro] read almost exactly the same as the Police device.

Verdict: If you drink, buy one. It’s a no-brainer, really."

“In the side-by-side comparison, the AlcoSense Pro proved to be as accurate as the larger machine [£13,000 Police breathalyser], as well as offering a number of innovations over other compact breathalysers.”

The Lorraine Show, ITV 1

“It’s very easy to be still over the drink drive limit in the morning; and the ‘Morning After campaign’ the Police have been running are picking up a lot more convictions now than they did 10 years ago. It’s worth getting yourself a DIY breathalyser. The AlcoSense Pro works very well and you can use it as many times as you like”.
