Contact SupplierThis type of device is a handheld alcohol breath-tester, designed to measure the alcohol concentration in a person’s breath (which correlates with blood alcohol concentration, BAC). It uses a built-in sensor (usually semiconductor, sometimes fuel-cell or hot-wire) and an LCD display to report the result in units such as % BAC, mg/L, ‰BAC. For example:
A device description: “The Alcohol Breath Tester is designed to measure the concentration result of the breathed alcohol in the human body. … When the alcohol content exceeds the preset limited level, this device will send an audio and/or video warning to remind you.
Typical usage: check yourself before driving, workplace safety checks, personal monitoring of alcohol intake.
✅ Key FeaturesHigh-precision sensor technology: Many units use a semiconductor sensor (or more advanced fuel-cell sensor) for detecting alcohol vapour in breath.
Alarm / warning when over limit: Many devices include a buzzer, indicator light, or visual warning if the measured alcohol exceeds a preset threshold.
Replaceable mouthpieces or non-contact design: For hygiene and repeated use.
