What is calibration?


Calibration is a process of adjusting the internal software so that the device can gauge specific blood alcohol concentration (BAC) levels. If the sensor becomes saturated, then the results of the device can become skewed. This is due to the fact that the manufacturer originally calibrated the device at a time when the sensor was unsaturated. The calibration process is similar to winding a clock. When the clock is first set it displays the accurate time. However, over time the clock can gradually drift a few minutes, and eventually can be off by a reasonable amount if you do not occasionally reset the clock. View a presentation explaining the calibration process.


When a unit is received by the Service Center the following items are evaluated: Battery Cover, Battery Wire/Connection, Display, Operation Buttons, Audio Alerts, and Mouthpiece Inlet/Outlet.


After diagnostic evaluation of the unit has been completed the accuracy is verified with a 2-point accuracy check and a Full Diagnostic Summary (pictured) is included with your unit, ensuring that it has been thoroughly inspected and returned to you in working order.

How often should I have my AlcoHAWK calibrated?


All digital breath alcohol detectors offered from AM Diagnostics come pre-calibrated, but it is recommended that you have a breath alcohol detector verified for accuracy every 1-12 months, depending on frequency of use. If you are using the breath alcohol detector multiple times daily, it is suggested to have the device calibrated at least monthly. If you do not use the breath alcohol detector daily but still use it several times a month, then it is suggested to have it verified at least every 6 months. If you use the alcohol detection only on rare occasions, then you should have it calibrated at least yearly. Calibration helps ensure that your device is operating correctly, and is an inexpensive way to greatly increase the useful life of your breath alcohol detector.

Why are regular calibrations needed?

Top 3 reasons for breathalyzer calibration:

  • Calibration will help your unit be more accurate

  • Calibration will help your unit last longer

  • Calibration will help identify any potential defects with the unit so they can be repaired immediately(\(\(Units under warranty are repaired or replaced at no cost to you)


AlcoHAWK Breathalyzers are precision instruments which will last longer and be more accurate if proper calibrations are performed. The AlcoHAWK Service Center operates with DOT certified solutions and trained technicians to calibration or repair your device.


Calibration is similiar to changing the oil in your car. Oil changes help keep your car operating correctly and help extend the life of your vehicle. Similiarly, calibration helps keep your breathalyzer unit operating correctly, helps maintain accurate results, and extends the life of the product. Calibrations, like oil changes, are a maintenance feature and are not covered under warranty.
