What is the UK drink driving legal limt currently ?

Blood Alcohol Concentrations (BAC) - 80 milligrammes of alcohol in 100 millilitres, 80mg/ml, 080 on mg/100ml display or 0.08 %BAC, 0.8 Promille

Breath Alcohol Concentrations (BrAC) - 35 microgrammes of alcohol per 100 millilitres of breath BrAC

What is the best buy for home breathalyser use ?

Higher price does not always mean higher accuracy, as the expensive breathalyser models are designed to be serviced regularly to maintain their accuracy and don’t have on board self diagnostics.

 Here are some key points to consider when buying a DIY digital breathalyser:

1) Insist on interchangeable sensors - without this you are tied to sending the breathalyser regularly to a service centre for calibration services.

2) The breathalyser must have selectivity of no less than +/-0.01% BAC which is the same as +/- 10mg/100ml BAC. (avoid units with +/-0.02% and over)

3) Choose your display scale and stick to it, most digital breathalysers either display as %BAC or mg/100ml BAC  (BAC=Blood Alcohol Concentration) don’t confuse this with BrAC .(Breath Alcohol Concentration) which is available but rarer.

4) Be realistic, under £25 and you are getting a novelty device which you should not rely upon. Expect to pay £35-£70 for a digital breathalyser which will work well, give reliable readings, cost £15-20 to replace the sensor (every 300 tests or 6 monthly)

Can I rely on the results when choosing to drive ?

No. Breathalysers should not be used to test your ability to drive legally, as a breathalyser will measure only your current blood alcohol levels. These can rise after testing if the unit is being used immeditaely after drinking. Breathalysers should be used the morning after to confirm that alcohol has left the body.

Breath tests for alcohol are widely available and work to set cut off levels, These are 0.02%BAC,(HSE occupational cut off) 0.05%BAC(European driving level) and 0.08%BAC (UK drive prosecution level)

The breathalyzer test kits are used once and then disposed into normal waste services.

Breath alcohol tests are available in packs of 3 and 6 and 20 tests. no specialist training is required to use the tests as a simple colour change confirms if the alcohol level is below the cutt off level or above it, making result interpretation simple.

The accuracy of breath alcohol test disposable breathalysers is very high at over 99% they are also stable and come with long expiry dates, making them ideal for users who may only need to test a few times a year or for a single event.

They are also the first choice for parents, wishing to police underage alcohol use.

The choice is large and often confusing, so we thought we would try to guide potential buyers with the key features to look for in a DIY digital breathalyser.

Higher price does not always mean higher accuracy, as the expensive breathalyser models are designed to be serviced regularly to maintain their accuracy and don’t have on board self diagnostics.

 Here are some key points to consider when buying a DIY digital breathalyser:

1) Insist on interchangeable sensors - without this you are tied to sending the breathalyser regularly to a service centre for calibration services.

2) The breathalyser must have selectivity of no less than +/-0.01% BAC which is the same as +/- 10mg/100ml BAC. (avoid units with +/-0.02% and over)

3) Choose your display scale and stick to it, most digital breathalysers either display as %BAC or mg/100ml BAC  (BAC=Blood Alcohol Concentration) don’t confuse this with BrAC .(Breath Alcohol Concentration) which is available but rarer.

4) Be realistic, under £25 and you are getting a novelty device which you should not rely upon. Expect to pay £35-£70 for a digital breathalyser which will work well, give reliable readings, cost £15-20 to replace the sensor (every 300 tests or 6 monthly)

Our recommendation remains the DA5000 for all round value for money and accuracy £39.99 with free UK delivery, low cost sensors and mouth pieces (for personal use you don’t need to buy extras, they are washable and re-usable) In our opinion this is currently the best value breathalyzer on the market for personal use.
