AlcoHAWK Calibration

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.

After diagnostic evaluation of the unit has been completed the accuracy is verified with a 2-point accuracy check and a Full Diagnostic Summary 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 Quest Products 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. 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.

Calibrations Needed?
