Breathalyzers – PEIYING AT551 Breathalyzer

Peiying AT551 Breathalyzer with Electrochemical Sensor

The Peiying AT551 breathalyzer is designed for all drivers who want to feel confident behind the wheel. The device is extremely compact, so you can easily store it not only in your car’s glove compartment but even in your pocket.

Precise in Every Situation

The Peiying AT551 breathalyzer owes its accuracy— ±0.05‰ at 0.50‰— to its electrochemical sensor , which is sensitive only to alcohol. The maximum display range is from 0.00 to 3.00 ?, and when this value is exceeded, the breathalyzer displays “HI.” Importantly, you can switch the measurement units to %, ?, or mg/L.

Intuitive Operation

Wondering which breathalyzer to buy? Choose a device that guarantees not only reliable results but also ease of use. One of the advantages of the AT551 breathalyzer is its quick readiness to take a measurement, as well as a short— 10-second — measurement time , with results displayed on a four-digit LCD screen . If the alcohol level exceeds the legal limit, the display will change color.

Battery Level Indicator

The device is powered by a AAA alkaline battery, which, combined with the auto-off feature , is sufficient for up to 300 measurements. Thanks to the low battery indicator, you can be sure the device won’t let you down in an emergency. Five mouthpieces are included in the set .

24 months of free calibration

The breathalyzer also features a counter for the total number of readings taken, which helps determine when recalibration is needed (after 12 months or after 200 readings). What’s more, when you purchase a breathalyzer for home use from our store, you receive 24 months of free calibration for your device.

A breathalyzer used for personal purposes (consumer purchase) can be calibrated free of charge and without limit within 24 months of the purchase date.
