Alcohol tester PEIYING AT551

Peiying AT551 electrochemical sensor of the breathalyzer
The Peiying AT551 breathalyzer is designed for all drivers who want to feel confident behind the wheel. The device is extremely practical, so it can easily fit not only in the glove compartment of the car, but also in your pocket.

Accurate in every situation
The Peiying AT551 breathalyzer owes its accuracy, i.e. +/- 0.05 ‰ at 0.50 ‰, to the electrochemical sensor, which is sensitive only to alcohol. The maximum range of the displayed value is from 0.00 to 3.00 ‰, and after exceeding this value, the breathalyzer displays the message "HI". Importantly, you can change the measurement units to %, ‰ or mg/l.

Intuitive operation
Are you wondering which breathalyzer to buy? Choose a device that guarantees not only reliable results, but also easy operation. The advantage of the AT551 breathalyzer is its quick readiness for measurement, as well as a short - 10-second measurement, the result of which you can check on the four-digit LCD display. As soon as the permissible alcohol level is exceeded, the display changes color.

Battery charge indicator
The device is powered by an AAA alkaline battery, which, in combination with the automatic shutdown function, is enough for up to 300 measurements. Thanks to the low battery indicator, you can be sure that the device will not let you down in a crisis situation. The set includes five mouthpieces.

The alcohol analyzer also has a counter of the total number of measurements taken, which is useful for calculating the recalibration time (after 12 months or after 200 measurements).
