Calibration/Servicing
Calibration Frequency:
Manufacturer recommendation for Personal use - at least every 12 months or 500 uses.
Australian Standards requirement for Workplace use - at least every 6 months or 500 uses, whichever comes first.
In-House Calibration
Out in-house technicians will specifically calibrate your breathalyser in accordance with Australian Standards regulations for the Australian/New Zealand legal limits.
Regular calibration is required to maintain the specified accuracy of each device. An in-built usage counter and an on-screen recalibration reminder make remembering to have your unit serviced simple.
Our flat-fee servicing cost includes return overnight freight. Turnaround is guaranteed 3-4 working days.
see Recalibration/Servicing page for further details.
Please Note: for accurate results users must wait at least 20 minutes after the cessation of drinking before testing. Use prior to this time will result in inaccurate readings and shorten the lifespan of the sensor.
