Breathalyzer Calibration

So what is calibration and when do I need to do it?

That's a question we get asked a lot. So here is the answer.

In order to keep your device working in tip-top shape you need to re-calibrate the device periodically. This ensure that the device remains accurate and provides reliable results.

Depending on the technology of the sensor, fuel cell or semiconductor, (to learn more about sensors click here) determines the number of tests between calibrations.

Generally speaking, you should calibrate a semiconductor device every 200 tests and a fuel cell breathalyzer every 500 tests. This is not an exact number, in fact many of our breathalyzers can do more tests than that before requiring calibration, but we err on the side of caution and this maintenance cycle will guarantee reliability.

What if you don't use it that often?

Regardless of the number of tests performed we recommend a minimum annual calibration. This ensures that even a low use device is working correctly.

How do I get my device calibrated?

Most models, excluding the Alcomate Premium AL7000 and the Alcomate Prestige AL6000 which both have replaceable sensors, require you to send the device to the manufacturer for calibration. This normally takes 10 business days in addition to the shipping time. The cost ranges from $19.95 to $50.00 dependant on the model and includes the return shipping cost to you.

When shipping your device out of Canada make sure you declare it as a "Repair/Warranty" on the custom and declaration form and enter the cost of calibration as the value.

Do not put the value of the device in this field as there will be additional charges levied.

Also, use a traceable and insured shipping service to protect your shipment against loss or damage.

Here are the appropriate forms to use when sending your device in for calibration:
