Quick-Response Portable Breathalyzer

This portable digital breathalyzer offers rapid, repeatable alcohol detection in a compact form factor: 11.8 × 7 × 2.8 cm, 52 g weight. It employs an advanced semiconductor oxide sensor with a measurement range of 0.00–0.19% BAC (0.0–1.9 g/L) and precision of ±0.01% BAC. Full sensor warm-up completes in under 10 seconds; test response occurs within 5 seconds. The backlit LCD ensures legibility day or night, and an audible tone confirms test initiation and completion. Runs on two AAA batteries (not included) and auto-shuts down to maximise battery longevity. Includes one device, four disposable mouthpieces, and an English manual.
