Please note we only calibrate Pro-line Breathalysers

Breathalyser Calibration is important!

Your breathalyser is a precision instrument using a fuel cell sensor to measure alcohol levels, regular servicing ensures ongoing accuracy and reliability while maintaining AS3547 standards.

Your Pro-line breathalyser uses a fuel cell sensor to measure breath alcohol levels and will require re-calibration.

The calibration period for your Pro-line fuel cell breathalyser is 6 months or 500 uses, whichever occurs first. If you receive erratic or high readings your breathalyser may need re-calibration.

Do not attempt to service it yourself. 

In order to keep your breathalyser in good working condition, we recommend that you blow into it at least once a month to ensure the sensor does not dry out.
