Breathalyzer Calibration

What is calibration?

Most breathalyzers no matter the make or model need to be calibrated eventually to keep the device producing accurate and consistent results. The calibration process is an adjustment to your sensor in the unit to make sure it is displaying a predetermined readout at a set BAC level. All you need to do is ship your unit to the correct manufacturer to be serviced for a small fee. Once a cleaning and adjustment to the software and sensor inside your breathalyzer unit is completed it is shipped back to you. The reason a calibration is needed is because your breathalyzer sensor can become saturated after many repeated uses and can begin to skew your readings, making your device inaccurate.

When do I need to calibrate my breathalyzer?

All breathalyzers sold by GS Solutions LLC are pre-calibrated before they are shipped to you so no calibration is needed right after purchase. Depending on the amount of use your breathalyzer gets it is recommended to have it calibrated every 1-12 months. We recommend that users who do testing on a daily basis send in their units for monthly calibration service. For any other breathalyzers with varied test amounts it will be between 1-12 months to keep the accuracy of your alcohol tester. If your device is used correctly according to the manufacturer’s directions and calibrated appropriately then you greatly increase the useful life of your breath tester.
