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.

Note: After ordering you will receive your personalized Calibration Certificates via email as a attachment it will be sent to the same email address you provide us with your order within 1 business days.

Great New Procedure

Certificate received via email vs USPS. As a former Postal employee I don't like for them to lose business but the new procedure is awesome. I myself have two PT500's and the last time I calibrated one of the units I watched the mail to get the Calibration Certificate to send in with the unit. It never arrived or thought it was "junk" mail and tossed. It was a big hassle to try to get a new certificate which I never did receive but the unit was already in the calibration process and documentation is questionable. Just wanted to say by emailing the Calibration Certificate it can't be lost and if it was ever deleted it could be resent. I'm impressed with the new procedure. Thanks for thinking of the consumer in changing the procedure.


Very easy

Very easy process, I received the certificate and sent it in with the breathalyzer it was that easy.
