Having your AlcoHAWK breathalyzer regularly serviced is a great idea and protects your investment, just as you routinely change the oil in your automobile to prolong the life of your engine. To ensure optimal performance we recommend sending your unit in for servicing (includes a full diagnostic check with calibration) at least once every 6-12 months depending on frequency of use and your testing protocol. 

What's included?
Once your AlcoHAWK breathalyzer is received our technicians will conduct a full diagnostic check and calibrate the device. The diagnostic check includes checking the battery cover, battery wire connections, display, operation buttons, audio alerts and mouthpiece inlet/outlet.

What is Calibration?
Over time, all breath alcohol detectors may need to be recalibrated. 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 or replacing batteries in 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.
