Is this breathalyzer accurate enough for post-drinking checks?
Yes. The device uses a high-sensitivity semiconductor sensor designed to provide dependable readings after drinking. It delivers fast results with reduced deviation, helping you assess your alcohol level before deciding whether it is safe to drive.
How do I understand the test results shown by this breathalyzer?
Result A: < 0.02% BAC = 0.10mg/L Green light-No alarm
Result B: 0.02% ~ 0.07% = 0.10 ~ 0.35mg/L Yellow light – Repeated “Beep Beep, Beep Beep” alerts
Result C: ≥ 0.08% BAC = 0.40mg/L Red light – Strong, continuous “Beep Beep Beep Beep…” alarm
How can I get the most accurate reading from this breathalyzer?
Avoid drinking, eating, or smoking 20 minutes before testing. Blow steadily for around 5 seconds and ensure the device has sufficient battery power.
Why are the readings different when I test several times in a row?
Avoid consecutive tests. Residual alcohol inside the sensor can affect the next reading. If the device hasn’t been used for a long time or has been used for months, it may need recalibration according to the manual.
Is it compact enough to carry during nights out?
Absolutely. The mini, lightweight design fits into pockets, small bags, or the glove compartment. It’s made for outings, gatherings, dinners and post-party checks.
