Breathalyzer PEIYING AT551

Все о продукте

The accuracy of the Peiying AT551, i.e. +/- 0.05‰ at 0.50‰, relies on an electrochemical sensor that is only sensitive to alcohol. Importantly, you can change the measurement units to %, ‰ or mg/l. The maximum range of the displayed reading is from 0.00 to 3.00 ‰. If this value is exceeded, the breathalyzer displays the message HI. In addition, the display will change color if the alcohol limit is exceeded.

The device is powered by an AAA alkaline battery, which, together with the automatic shut-off function, is sufficient to perform up to 300 measurements.
