Calibration of breathalysers is recommended to maintain the accuracy of the sensor which measures your breath alcohol content.

Calibration is done in-house for all the breathalysers that we supply.

We use two different methods for calibrating - wet bath and dry gas.

Calibration is recommend every 6-12 months.

See FAQ tab for more information about calibration.

  • Why do breathalysers need calibrating?
    • All alcohol breathalysers need regular calibration to ensure their accuracy. Calibration is performed by using ethanol at a set point to test the breathalyser against. This is to ensure the sensor is reading as it should.
  • Where do I send my breathlayser for calibration?
    • Courier it in to us -
