Breathalyzers with tests counter

Tests counter

— built-in counter that records the number of measurements taken. The features of the operation of such a counter can be different — in particular, it can count from the beginning of the day, from the moment it was turned on, from the moment the sensor was last calibrated, etc. These details should be clarified separately. Anyway, the meaning of this function lies in the fact that most breathalyzers have restrictions on the number of measurements per day, and without automatic counting, it can be difficult to monitor compliance with these restrictions. In addition, the calibration and maintenance of the sensor also needs to be done after a certain number of measurements.
