Breathalyser Calibration

Breathalyser Calibration

Breathalyser calibration what is it?

Calibration of breathalysers is the process of checking and adjusting the alcohol sensor within the breathalyser to ensure the reliability, and that it can be trusted to give consistent accurate results. The main goal is to minimise any measurement uncertainty

Why is it important to get a breathalyser calibrated

It is important that the calibration is carried out by a UKAS (United Kingdom Accreditation Service) accredited organisation following the guidelines ISO/IEC 17025:2017 which provides an assurance of the competence, impartiality of conformity in that service.

How often should a breathalyser be calibrated

The recommended frequency of calibration is every 6 months, some devices having software that stops the device working at exactly that time.

What is involved in the calibration process

The process of calibration involves sending the device to the UKAS accredited organisation which will carry out a QA/Drift test and issue a certificate, calibrate using a wet bath calibrator and issue a certificate of calibration and then send back at the earliest opportunity to avoid being without a device.
