The New AlcoSense Lite 2

At a glance:

  • AlcoSense’s Entry Level Breathalyser
  • Easy to Use, clear results in seconds
  • Intermediate level semi-conductor alcohol sensor
  • Adjustable drink drive limit to any UK or Irish limit
  • Pocket Sized - (HxWxD): 110 x 45 x 21mm
  • Does not measure breath sample volume or flow

Designed in the UK by AlcoSense’s award winning team, the AlcoSense™ Lite 2 is the successor to the highly acclaimed AlcoSense™ Lite (What Car? Best Breathalyser under £40, Road Safety Analysis Group Test Entry Level Winner, Diesel Car Group Test Runner-Up to AlcoSense™ Elite).

Like all AlcoSense™ products, the Lite 2 has been designed to be as easy as possible to use. To do a breath test all you need to do is turn the unit on, wait for it to count down to zero and then blow until it beeps. Easy!

Designed in Britain with exceptional pedigree

Designed in Britain by AlcoSense Laboratories, the AlcoSense Lite 2 is the successor to the highly acclaimed AlcoSense Lite.

The Lite 2 has a new sleek, pocket sized design. Measuring only 110mm high x 21mm deep x 46mm wide and weighing less 150 grams (including batteries), it can be discretely carried in a pocket or handbag.

Any Limit in Ireland, Scotland or the rest of the UK

The AlcoSense™ Lite 2 reads across all limits currently used in the UK and Ireland and the don’t drive alert can be adjusted by the user to any of those limits.


Easy to Understand Results

AlcoSense™ Lite 2 shows your level of intoxication in ‰BAC (promile blood alcohol content) in increments of 0.1 (If you require a more detailed readout or in mg/L please see the AlcoSense™ Elite 3).

The AlcoSense™ Lite even alerts you when you are close to or over the user-set drink drive limit.

Under the limit the result is displayed in increments of 0.1 ‰BAC

Close to and over the user-set limit, the result is displayed with a don’t drive alert


Sleek Pocket-Sized Design

The AlcoSense™ Lite 2 comes from the same design team that developed the AlcoSense Excel, Pro and Ultra, winners of the 2018 German Design Award and the 2016 Red Dot Product Design Award. Pocket sized, it can discretely be kept anywhere. AlcoSense™ Lite 2 measures only 110mm (height) x 45mm (width) x 21mm (depth). It is powered by 3 x AAA batteries meaning that you can use it anywhere at any time.

Easy Maintenance and Recalibration Alerts

The AlcoSense™ Lite 2 has an ASC feature, manually selected by the user, which is a deep clean of the sensor and should be undertaken periodically to remove contaminents like residue and oxidisation from the sensor.

The Lite 2 now also features a calibration reminder after 12 months or 300 tests so you can easily remember to have your breathalyser recalibrated and ensure ongoing accuracy.


Use it Again & Again

Using the latest semi-conductor sensor technology and innovations AlcoSense™ Lite 2 can be used up to 300 times between calibrations meaning you will never be caught short. Please note, the Lite 2 does not actively clear residual alcohol from the sensor after each test meaning that you must wait 5 minutes between tests. If you wish to test more frequently than this please consider one of our models higher up the range.


Every AlcoSense™ unit is tested for accuracy three times before leaving our factory. As a result, our quality control is arguably the best in the industry meaning that you can have 100% faith in our products.

AlcoSense™ Lite2 has industry leading accuracy at this price point of +/-0.2 ‰BAC. Please note: the Lite 2 does not measure breath sample volume or flow rate which increases the accuracy of the readings, if greater accuracy is required please see our models further up the range.


Why Delay?

Part of the responsible enjoyment of alcohol is to understand its effect on the body and to understand when you are safe to drive, AlcoSense™ helps people do exactly that and takes out the potentially fatal guess work the morning after. Don’t leave it to chance, order yours today.

Easy to use

by Buzzkokk on 08/12/2019

Easy enough to use. Just a bit confused about having to use a switch in the battery compartment. When I opened the compartment I couldn't find a switch. With an accuracy of +/-0.2% and a U.K. limit of 0.8%, it's possibly 25% inaccurate. This is a guide and not to be taken as gospel
Does what it says on the tin! Well designed. Easy to use. Clear instructions

by Karlos on 07/12/2019

Does what it says on the tin. Excellent product. Well designed. Clear instructions and easy to use.
Incredible piece of kit

by AndyB1964 on 07/12/2019

This device helped me after i was drinking the night before. Even told me "Do not drive" when i tried too early. Tried again later and it said I was good to go. Highly recommended

Great buy!

by Kirky87 on 27/11/2019

Purchased this product a week ago and really impressed. A family member used to have the Elite version which was very chunky (and noisy!) and the Lite 2 is very sleek and not as loud!
It provides a reading within seconds, is small enough to keep in your car or bag for those moments when it's best to be safe than sorry! Would highly recommend.
Easy to use

by Red Tam on 22/11/2019

Have used twice and both times read lo. Very easy to use.

Great way to ensure your safe to drive

by rfarrelly67 on 19/11/2019

This is our 2nd personal breathalyser and although we don't drink a lot, on the odd occasion we go out, I want to be sure that the morning after, we are under the limit before we get in the car. A great breathalyser to give us 100% peace of mind!

Everyone should have one

by Edward C on 21/09/2019

Should have bought this sooner. When you are out you can loose count of what you have drank. Not knowing is very risky.
Peace of mind

by Mark bus driver on 15/09/2019

I just opened the packet and read the instructions. It is so simple to use and yesterday I was out for lunch and had a beer. I wouldn't normally drive after 1 beer. My daughter was stuck and needed a lift later in the evening. I tested and blew 0.3 so instead of getting her a taxi I was able to confidently get her myself. I will be recommending this to my colleagues.
Very handy product.

by Peter Benison on 28/08/2019

It was easy to set up and is really simple to use. A very handy product to have as it can be surprising how much alcohol is still in your body the next day.

Great product and great price
Excellent device

by Archie on 14/08/2019

Seems to be just as good as the Elite I had before. Lent that to a friend who promptly lost it but he was so impressed he bought two of these, one to replace the one he lost. I doubt there is much difference between the two but, its always nice to have the latest model.
Excellent product for New Irish limits

by Baz on 07/08/2019

Excellent performer for such a low price. The AlcoSense Lite 2 can be set up for Irish limits. This covers adults and new learner drivers. Great for morning after
Excellent small device

by Will on 06/08/2019

A really useful and compact device that will be very helpful in knowing if one's safe to drive. Very good value too.
A little tricky learning how hard to blow to get a reading, but that's not really a problem.
Does the job and easy to use.

by Sarah O on 05/08/2019

Very east to set up and use. It’s small and neat.
Results are clear and helpful.
Takes away the guesswork the morning after - great product!

This is a great device that is very easy to set up and use, giving fast results. Great to understand how your body processes alcohol and if you might still be over the limit in the morning.

by Rose on 22/07/2019

Handy little device, straight forward to use.
Well worth the money to ensure you are within the legal limit to drive.
Updated to the lite2

by David on 06/07/2019

I had the previous lite model and decided to replace it with the new lite 2. Easy to set up and I really like the new design with it larger screen making the readings easy to read.
I use it in the mornings to check that I am legal to drive.
Quick delivery and easy to use

by Gill on 29/06/2019

It was tricky to see the BBR switch, but once found the rest was easy. Needs a good blow to register the reading, but clear and simple to use. Should prove to be a useful and reassuring device
