The portable breathalyzer tester is easy to use. To start the professional breathalyzer alcohol tester, simply press the power button for 2 seconds. Wait for 20 seconds for warming-up, then blow with the home breathalyzer for 5-6 seconds. The result will be ready after 3 seconds and displayed on the LCD screen for 15 seconds.

The portable Breathalyzer features a smart alarm function and energy-saving design. When the test result is higher than 0.05% BAC / 0.5 ‰ BAC, the red light of the digital breathalyzer flashes and emits a continuous drop sound to remind the user. The home breathalyzer is powered by 3AAA alkaline batteries (not included) and will auto power-off to save power after finishing the test for 5 seconds. It also has a low voltage indication.

Note that for accurate test results, it is recommended to wait 20 minutes after drinking alcohol before using the portable breathalyzer. Also, wait for another 3 minutes before starting the next test to get a precise alcohol testing result.
