Ultra at a glance:

  • 200mm2 Fuel Cell Sensor – same as several UK, EU & US Police sensors
  • More than twice as accurate as award winning AlcoSense Elite
  • Selectable database of all drink drive limits worldwide
  • Download results to your PC
  • Blow Coach making it extremely easy to use
  • Winner – 2016 Red Dot Product Design Award

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

Police Pedigree

The AlcoSense Ultra is the first consumer breathalyzer in the world to use the same 200mm² professional fuel cell alcohol sensor as several UK, US & European Police Breathalyzers.

Professional Sampling System with Temperature Compensation

The AlcoSense Ultra uses a professional grade sampling system to ensure that only deep lung air (the most accurate part of the breath) is measured by the sensor. It uses professional grade 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 Ultra to get clever with BlowCoach™

Alcosense Ultra

Memory Recall & PC Connectivity

The AlcoSense Ultra will store 128 results in its on-board memory with date and time stamps, using USB and AlcoSense’s software (available early 2016) the results can be downloaded to your Windows PC for analysis and record keeping.


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 Ultra 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 too softly Blowing at too softly
Blowing correctly Blowing correctly

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

Blowing too hard

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 Ultra has some clever software to eliminate the downside – i.e. instead of having a tolerance of +/-0.10‰BAC, the AlcoSense Ultra’s tolerance is +0.07‰BAC, -0.00‰BAC. This means the Ultra will read a little on the safe side, not too low and more three times as accurately as the award-winning AlcoSense Elite.

Any Limit in the World – Literally

At a click of button the AlcoSense Ultra 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 Ultra 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.

AlcosenseUltra choose country

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.

AlcoSense Pro Breathalyser

Detailed, Easy to Understand Results

AlcoSense Ultra 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 Ultra will alert you not to drive.

No alcohol No alcohol
Up to 80% of the limit Up to 80% of the limit
Close to or over limit Close to or over limit

Time Until Sober & Retest Alarm

AlcoSense Ultra 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 Ultra will alert you to retest again later.

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

Memory Recall

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

Backlit “Twin” Blow Tube Receptor

The Ultra features a backlit blow tube receptor so it’s easy to put a blow tube even in low light. The Ultra 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.

Ultra Backlit

Re-Calibration Alert

Any breathalyzer requires re-calibration after a period of use, the AlcoSense Ultra has an industry leading calibration period of 12 months from the first time you use it. To improve reliability and user friendliness AlcoSense Ultra 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 Ultra 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, and the sensor becomes 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 Ultra will enter a protection mode which allows the sensor to recover before allowing further tests.

Quality & Reliability Assured

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

The Guardian Breathalyzer Review

 "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."

"The most accurate over-the-counter device currently available...Even compared to the hugely complicated static devices found in police stations (worth upwards of £10,000), the reliability and accuracy of the AlcoSense Ultra is hugely impressive, partly thanks to a new software calibration technique that prevents the device from under-reading.However,it is the day-to-day usability of the AlcoSense Ultra that should be its main selling point"

"...the device enables you to select literally any drink drive limit from around the world (from Australia to the UAE), making it the perfent partner for cross-country road trips,"

'Combined with its stylish and ergonomic design (the blowhole, for example, lights up for ease of use in the dark) the AlcoSense Ultra more than justifies its price making it a must-have for those who truly value their licence.."

Alcosense Ultra

by Allan on 10/06/2021

I have now had three Alcosense breathalysers and have full faith in them as a great aid for the day after.
12 hours between bottle and throttle is a good idea. Alcosense assures me that I'm ok and I feel safe.
