Description Description: A breathalyzer or breathalyzer (a portmanteau of breath and analyzer/analyzer) is a device for estimating blood alcohol content (BAC) from a breath sample. It uses advanced semiconductor alcohol sensing technology to quickly take a breath sample and provide a blood alcohol content (BAC) estimate. The LCD graphic display will indicate how inebriated you are whether it be dangerous (over 0.05% bac) unsafe (approx. 0.02% bac) or safe (under 0.02% bac). Displays caution when result is within 0.02% - 0.05% displays danger when result equals to or higher than 0.05%. Features: High sensitivity semiconductor alcohol sensor. One-key operation automatic shutdown power saving. Digital blue backlit LCD display. Quick response and recovery function. Automatic sound alarm-portable design. Intelligent MCU control. Specifications: Sensor:Advanced semiconductor oxide alcohol sensor Test range: 0.00-019% BAC (0.0-1.9g/l) Working temperature: 5 to 45C Accuracy: -0.01% + 0.02% BAC Alarm threshold: 0.50% BAC Power Source: 2 x AAA batteries ( not included ) Response time: 5s Working time: 10s Warm up: 10 seconds Automatic power off: 10 seconds after the result is displayed Tips: In order to obtain a more reliable record it is recommended that you take the test at least 20 minutes after drinking. In addition please wait at least 3 minutes for the next test to start after the previous test.
