Alcohol Interlock Calibration: Ensuring Accuracy in Alcohol Interlock Devices

Alcohol measurement is a delicate process. You must regularly test and adjust a breathalyzer to ensure it maintains the proper sensitivity to alcohol, neither too low nor too high. We call the calibrated part of the alcohol testing device the fuel cell. We designed this component specifically to detect ethanol and can adjust it for greater specificity. Usually, calibration is done by exposing the breathalyzer to an alcohol vapor of a precise and pre-determined concentration and changing the breathalyzer or alcohol interlock device to reflect that amount of alcohol.


Suppose you require an alcohol interlock on your vehicle. In that case, its mechanism to calculate your mg/l or BrAC is similar to a police breathalyzer, using the same fuel cell technology to detect alcohol.

The Importance of Regular Calibration

When you calibrate your alcohol interlock device, the technician will make sure that it’s registering alcohol vapors accurately. Local regulations determine precisely how accurate the alcohol interlock must be, and technicians are required to test and calibrate every device for monitoring. At LifeSafer Alcohol Interlock, we also repeatedly calibrate and thoroughly test every unit before sending it to the field for use in your vehicle. We know how important it is to get an accurate reading every time.

What does an alcohol interlock do?

An Alcohol Interlock tests for the presence of alcohol in your breath. If it detects alcohol, it prevents your car from starting. Some alcohol programs may require to take periodic tests during your drive (random rolling retests), an alcohol interlock device will never stop your car while you are driving.
