Calibration Centers

It is recommended that you calibrate your breathalyzer once a year or based on the number of tests performed as per your device’s instruction manual and/or maintenance schedule. Only qualified technicians should perform maintenance of any breath alcohol tester.

Below is a list of Calibration Centres that can calibrate the majority* of breathalyzers sold by APC. We recommend that you consult the instruction manual of your device and contact the center of your choice before presenting yourself.

*Please visit ACS for DRIVESAFE breathalyzers or contact Alco Prevention Canada au 1-888-863-8660.

Over time, all breathalyzers, need to be calibrated. The calibration process adjusts the internal components letting the breathalyzer measures BAC (blood alcohol content) correctly, and this, at all levels detectable. If the sensor is saturated, the breathlayzer’s results may be biased. The calibration process is similar to the adjustment of a clock. When the clock is well adjusted, it displays the time precisely. By contrast, over time, the clock can lose little by little, a few minutes here and there and then eventually no longer display the correct time.

When we receive a breathalyzer for calibration, all of the following items are evaluated: battery (ies), connection wires, display, operation of the buttons, sound, mouth input / output. Following the calibration, we verify the accuracy of the results.

Your breathalyzer comes precalibrated, but it is recommended to check your device after a number of tests or months of use. Since each device is different, we recommend that you consult our FAQ or your guide for instructions in order to know the frequency of calibration for your device, since the latter may vary from 100 to 1000 tests or 6 to 1 year.

If you rarely use your breathalyzer, calibrate it once a year. The calibration process ensures that your breathalyzer is working properly and its an economical way to significantly increase the life of your breathalyzer.

If you bring your alcohol detector to our offices and you just the retrieve, the cost of the calibration service is $34.44, including taxes, EXCEPT for DRIVESAFE models. DRIVESAFE models are sent to the manufacturer and the calibration cost is higher. An agent will inform you when we will receive your device.
