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.
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.
