Breathalysers

Breathalyser types

Alcohol testers with a semiconductor sensor - these testers are suitable for occasional use. You have to breathe directly on the tester’s sensor. The sensor in this type tends to wear down over time, requiring a replacement.

Alcohol testers with an electrochemical sensor - this type is more expensive and is used by the police or employers who need to supervise their employees on a daily basis. In this case, you don’t need to breathe directly on the sensor; the tester automatically samples the air necessary for analysis. This method is easier on the sensor, which gives it a longer lifespan.
