The smallest breathalyzer with the greatest precision. The ACE XS breathalyzer is small but impressive! While competitors from the Far East use only inaccurate semiconductor sensors, the ACE XS is equipped with an electrochemical sensor. These sensors are also used in the well-known preliminary tests conducted by the police due to their high precision! With a height of just 6 centimeters and a weight of only 60 grams, the ACE XS, developed in Bavaria, is a small marvel of technology. It makes an ideal gift for responsible drivers!

Extremely fast and easy to use. While the sensors of other breathalyzers need to warm up, the ACE XS already displays the result of the breath sample. This super fast and simple operation is unmatched at this level! All functions (breath sampling and switching between units of measurement such as promille, BAC, or mg/L) can be accessed with just one button. Thus, the small ACE XS is perfect for taking along in the car for self-testing the morning after! Its detachable keychain fits most car keys.

Calibration for accurate results. Like all our breathalyzers, the ACE XS is calibrated before shipping! We recommend calibrating it about twice a year or more frequently with very regular use. Of course, the ACE XS also works without regular calibration! However, the results may become less accurate and less consistent over time (drift). We recommend using a new mouthpiece for each test, not only for hygienic reasons but also to avoid contamination of results by residues!

Developed in Germany by the market leader. As the leading breathalyzer manufacturer in Germany, we invested two years of development time into the ACE XS. Our new breathalyzer is fast and sleek like a sports car, thanks to its GT design! The ACE XS was developed in Freilassing, Bavaria, where we also calibrate our devices.
