The AlcoSense Single Use Breathalysers come in a Pack of 12 and are quick and easy to use. They contain silica crystals impregnated with a secret formula which turn from yellow to green in the presence of alcohol. If the colour change reaches the red line then you are over the set limit.

The AlcoSense Single Use Breathalyser can help you monitor your alcohol level against all the limits in place in the UK and Ireland, including the lower Scottish limit. Be alerted at more than one level of intoxication, including:

  • 0.2% BAC for the Irish Professional Driver and Eastern Europe Limits
  • 0.5% BAC for the Scottish, Irish and Continental European Limit
  • 0.8% BAC for the English and Welsh limit

Quick and easy to use, the patented crystals inside the tube change colour from yellow to green in the presence of alcohol. Results show in just two minutes, and the Breathalysers use a blow bag to make sure the right volume of deep-lung air passes through the tester. Too little air equals a falsely low reading and too much creates a falsely high reading. The blow bags in the AlcoSense Single Use breathalysers eliminate this issue to provide the most accurate reading.
