BACtrack Breathalyzer Calibration Instructions

To ensure optimal performance, all breathalyzers must be calibrated periodically. Calibration is a process in which a trained technician adjusts the software inside the breathalyzer so that it measures BAC levels accurately.

About Breathalyzer Calibration

The BACtrack calibration process is a delicate one, requiring a trained lab technician in a controlled environment. Known alcohol concentrations are passed through the sensor to set baseline values for testing. Technicians ensure the unit’s accuracy at all levels of intoxication.

But that’s not all you get with a BACtrack calibration--we also run each unit through a full diagnostic test, which includes a mechanical check, an air flow check, and an accuracy check. After these tests are completed, the accuracy is verified with a double blind point-to-point assessment.

When to Get your BACtrack Calibrated

If your breathalyzer is providing inconsistent test results, is not providing any test results, or provides unusually high or low test results, the product should be calibrated immediately by a trained professional. Not calibrating the unit per the suggested time frames can harm the sensor.

BACtrack recommends that you calibrate your Pro Grade breathalyzer at least every 12 months, while the non-Pro Grade units may need servicing closer to every 6 months; depending on the performance you observe and require. If the breathalyzer is used every day, it may need to be calibrated more frequently.
