The Calibration Service fee is $23.95 (plus $10.00 return shipping). Once received by the Calibration Department, your unit will be calibrated, tested and returned to you.
PAS Systems recommends that you have your portable breath tester calibrated annually or after every 250 tests. Because precise calibration is crucial it can be performed only by PAS Systems International. Calibration of your personal breathalyzer unit must be performed using a NHTSA-approved wet bath simulator.
