As with any precision instrument, periodic calibration is required to ensure instrument accuracy. Calibration adjusts the internal settings of your alcohol tester to a predetermined and known standard.

Lifeloc recommends instrument calibration at least annually to ensure test accuracy and precision. We can do this for you or provide you the equipment so that you can perform your own calibrations either manually or automatically. Your organization may have additional calibration procedures that you will need to adhere to.

It is important that calibration instructions are followed precisely. Every manual calibration must be followed by a manual calibration check to make certain your unit is properly calibrated. These procedures are available in detail in your Operator’s Manual. Alternatively, Lifeloc instruments can perform automatic calibration and cal checks when used with the Lifeloc EASYCAL® G2 Automatic Calibration Station.

If your unit is used under Department of Transportation guidelines, Lifeloc has DOT approved Quality Assurance Plans (QAPs) that will help guide you through the process. Please note that in order to perform a qualified calibration on units used for evidential DOT testing, you must be certified through Lifeloc or a qualified instructor as a factory authorized Operator and Calibration Technician on the specific model you are using.
