Portable Breath Tester Semiconductor Sensor

Dimensions: 95 x 36 x 18 mm; weight: lightweight handheld design. Measures breath alcohol concentration (BAC) from 0.00% to 0.19% with 0.01% BAC accuracy using an advanced semiconductor oxide sensor. Powered by two 1.5V alkaline batteries (not included). Features a 10-second warm-up time, response time under 5 seconds, and automatic power-off after approximately 35 seconds. For reliable results, wait at least 20 minutes after drinking or eating before testing, avoid exposure to solvents or irritants, and allow at least three minutes between consecutive tests.
