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

For workplace alcohol testing, regular calibration is required to remain compliant with standards.

Calibration is carried out in-house for all the breathalysers we supply, using both wet bath and dry gas methods. Calibration is required every 12 months for the Lifeloc LT7, and every 6 months for other breathalyser models, in accordance with AS 3547:2019.

If your model isn’t listed on our site, please get in touch. Our team can confirm if calibration is available or discuss alternative options.

We also occasionally have refurbished breathalysers available. If you’re interested in purchasing one, let us know and we’ll advise what’s currently in stock.

Book your breathalyser calibration by completing the form below. Include your details, then send your breathalyser to us. Once received, we will calibrate and return it within 24 – 48 hours.
