compartment of the car, but even in your pocket. The advantage of the AT551 breathalyzer is the quick preparation for the measurement, as well as the short measurement of 10 seconds, the result of which can be checked on the four-digit LCD screen. The accuracy of the Peiying AT551, i.e. +/- 0.05 ‰ at 0.50 ‰, depends on the electrochemical sensor, which is sensitive to alcohol only. Importantly, you can change the units to%, ‰ or mg / l. The maximum range displayed is 0.00 to 3.00 ‰. If this value is exceeded, the breathalyser displays the message "HI". In addition, if the alcohol level is exceeded, the screen will change color. The breathalyzer also has a counter for total measurements taken, which helps to calculate the recalibration time (after 12 months or after 200 measurements). The device is powered by an AAA alkaline battery, which, together with the auto-off function, is sufficient for up to 300 measurements. With a low battery indicator, you can be sure that the device will not disappoint you in an emergency. The set consists of five mouthpieces.
