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 setup and use

by RK on 16/01/2020

I bought the Alcosense lite 2 breathalyser to use the morning after a family wedding. It was very straightforward to setup and to use. Would highly recommend.
Great product

by tonyod on 13/01/2020

Great product which is easy to use and great reassurance at a reasonable price.
Really good

by Lisa P on 12/01/2020

I bought this to ensure I didn't drive too early after work hospitality events. Its small, light and easy to use and not that expensive versus other versions, but same accuracy.
Classy, small & effective

by Jennyfrase on 12/01/2020

Looks really nice, small enough to fit in glove box neatly, i think everyone should have one of these!
quality, compact and reliable

by Mike P on 08/01/2020

I have had various of these over the years from cheap non reliable key ring versions to some more expensive when they started becoming handlheld large units but this one is a a good size and very impressed with the quality. The cost is very palatable and straws are cheap for the number of times I and indeed some friends have needed to use it when driving next day to ensure We are under the very low Scottish limit!

by ingli on 08/01/2020

nice looking and easy to use
Compact easy to use

by Lisa on 07/01/2020

Great little kit for that piece of mind

by ryanmck1984 on 06/01/2020

This was an upgrade from my alcosense lite that i had used for 2 years. Great design and easy to use. Good that the percentage can be changed manually depending on what country you need it for. Would definitely recommend.

A great product I found very useful throughout the "silly season" it gave me peace of mind that I was safe driving the morning after. Such a great device, so handy to use and a good clear display
Excellent Product, would highly recommend.

by Sam P on 04/01/2020

I bought this product as I regularly host hospitality events and wanted to ensure I wasn't over then limit before i drove the following morning. It is so simple and easy to use and great value for money.

Tested this the evening it arrived and was really pleased to see it produced the exact results we were expecting... it’s great to have this to confirm what we were thinking.
Peace of Mind the Morning After

by Bunks on 03/01/2020

I bought a "lite II" after (for curiosity's sake) using my Brother's older machine on Boxing Day I would not have been fit to drive until well into the afternoon. I used my new box of tricks to test my self imposed limit, it showed that I have a significant safety margin against prosecution even if I drove in Scotland. The machine is simple to use and has a nice bright display. If you live in Scotland or other lower limit country a machine like this is essential for the morning after.
A really good and simple tester

by Sandyd on 01/01/2020

Simple to set up. Simple to use. This is our second one after the previous model (no longer available) expired. User manual was clear, straightforward and we were able to use it in minutes.
Great product

by Kevin Granger on 01/01/2020

I am really happy with the AlcoSense Lite 2. It was very useful during Christmas and New year's for reassurement of compliance with drink driving law. Simple and easy to use.

by Wise owl on 31/12/2019

by Helen on 24/12/2019

Very simple to use, and a good safety morning after check before driving.
Essential piece of equipment

by Stonecold on 24/12/2019

Decided to buy this breathalyser as it appeared to be good quality for a very reasonable price. Like most people I just want peace of mind that I am not over the limit the morning after, also am planning a driving holiday through France where it is mandatory to have one in your car. The build quality is very good and the instructions are clear and concise.
Works great

by Benj on 23/12/2019

Tested myself before driving after a good drink the night before and gave me a clear reading that I was OK to drive
A great find!

by steadyeddy on 23/12/2019

Just bought the alcosense lite 2. I tried it the morning after a few beers, i felt fine to drive, but after using the breathalyser, it alerted me that i was still over the limit, needless to say, no driving for the rest of the day. Great gadget!
First Class Product

by Steveo No 1 on 23/12/2019

We purchased this product as we have seven drivers at home and it is the party season mainly for the following days driving , We can strongly recommend this to anyone First Class Product and simple to use. So far we have all tested under the limit but it gives you a confidence boost.

Great product, compact and portable

by Niall on 17/12/2019

I've always been someone who will never drive if I'm not sure, but this product adds a level of assurance when I'm making a decision to hello me make the right one.
Great product at a great price

by Elaine on 16/12/2019

Excellent product and very easy to use. Very good value also. I work for a wine and spirit company and it is great to have it in the car if I have done a tasting with customers. It makes you much more aware.

by sandis on 16/12/2019

Works fine

by Macnib on 16/12/2019

I was given this by my wife as a birthday present
For the simple reason that I don’t drink very much even when I am the very rare non driver.
The logic being that I am wasting the non driving opportunity by not drinking enough,!
Very nice piece of kit, simple to setup and use.
Great to check you levels after a few lunchtime drinks before driving later.
Always drive safe.

Just the job

by SpratleyB on 10/12/2019

Great way to keep you safe

by Bizey on 10/12/2019

Great value for money and the security of knowing you’re safe to drive. Easy to use.
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.

speedy delivery service received from this company. Product itself really easy to use delivers fast and accurate results would highly recommend
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.
Excellent Product

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!

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.
New release

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
