Overview

The ACE OF SWEDEN ACE Alcohol Tester II is a compact breathalyzer designed for reliable self-testing. It uses an electrochemical fuel cell sensor, the same technology trusted by law enforcement, to measure breath alcohol concentration from 0.00 to 4.00‰ BAC. The backlit LCD shows results in ‰, % BAC, or mg/L, switchable to suit your preference. Warm-up and response times are both approximately 5-10 seconds, so you get a reading quickly. Powered by two AAA batteries, it delivers up to 500 tests before replacement. The device includes a flow sensor to ensure a proper breath sample and an automatic shut-off to conserve battery life. A test counter and battery status indicator keep you informed of usage and power. Five mouthpieces are included for hygienic testing. Calibration is recommended every 6-12 months or after 500 tests to maintain accuracy.
