?High sensitivity?High Sensitivity and advanced semiconductor technology, this breathalyzer is precise to the within a hundredth of a percent.Please test after drinking for at least 20 minutes because it takes about 20 minutes for the alcohol to be absorbed from the digestive into the bloodstream. If testing immediately, it can only reflect the alcohol concentration in the oral cavity, not in the blood??Easy Handling?Our professional breathalyzer is overwhelmingly easy to use. Breathalyzer just one-button operation, it's easy to turn the device on and test it in seconds.?Portable alcohol breathalyzer?Space saving, lightweight, completely easy to hold and carry everywhere.?For more accurate measurement readings: ? Do NOT smoke or eat within 20 minutes before testing. ? The test time should be after 3 minutes from the last test.
