Calibration is a periodic procedure that is required by traditional breathalyzers in order to maintain function and accuracy.
If you own a handheld AlcoMate breathalyzer not including the Revo, Premium or Prestige, your device must be re-calibrated approximately every 200 tests (1000 tests if it is a fuel-cell device) or at least once per year, whichever comes first.
If you own an AlcoMate product featuring PRISM technology, you will never have to return your device for re-calibration. You must still replace the sensor module on schedule, but replacement is quick and easy, and you can enjoy the assurance of long-term accuracy that manual re-calibration cannot provide.
You can return your device to the address below along with a check or money order in the amount of US$35 (US$50 for the AccuCell):
