How do I know when I need to calibrate my breathalyzer?

Last Updated: Apr 17, 2019 09:07AM PDT
If your product is providing inconsistent test results, is not providing any test results, or provides unusually high or low test results, the product should be re-calibrated immediately by a trained professional. Not calibrating the unit per the suggested time frames can harm the sensor.
How often your breathalyzer needs to be calibrated depends on two things: which BACtrack unit you own, and how often you use it. The Pro  Grade breathalyzers all have long lasting fuel cell sensors. We recommend that you send them in for calibration about once a year. The non-Pro Grade breathalyzers all have semiconductor sensors, for which we recommend calibration about once every six months.

It’s also worth remembering that if a breathalyzer isn’t used for a long period of time—say, 3-4 weeks—the sensor can dry out. We suggest that even if you don’t plan on using your breathalyzer for a while, breathe into it at least once a month in order to keep the sensor moist and in good working condition.
