Why you'll love it
Fast, accurate readings. A high-precision semiconductor gas sensor and advanced sampling algorithm deliver a stable result from a single 3-second breath — no waiting, no guesswork.
Simple, one-button operation. Turn it on, blow, read the result. A bright 1.33" LCD display and voice announcement make every reading clear, day or night.
Instant traffic-light feedback. A green, yellow, or red indicator light shows at a glance whether you're in the clear, in the caution zone, or over the limit.
Multi-unit display. Switch between %BAC, g/L, mg/L, and mg/100mL at the touch of a button, so it's ready to use correctly wherever you are — US, Europe, or Japan.
Built-in memory. One-click access to your test history lets you review previous readings in order, right on the device.
Self-cleaning technology. An automatic high-temperature cleaning cycle keeps the sensor accurate test after test, with no manual maintenance required.
Small enough to carry anywhere. At just 120 x 59 x 20 mm and 66 grams, it slips easily into a pocket, bag, or glovebox.
