• How do I calibrate my Hanwei breathalyzer?

  For models like the AT808, it is recommended to calibrate the device every 2000 tests or at least every 6 months to ensure sensor accuracy. The device will usually display 'CAL' when calibration is due.

• What app does the Hanwei alcohol tester use?

  Hanwei Bluetooth-enabled breathalyzers, such as the AT808, use the AlcoCHECK app, which is available on both Google Play and the Apple App Store.

• Why is my Hanwei gas detector showing a yellow FAULT LED?

  A yellow fault light typically indicates that the sensor is faulty, out of scale, disconnected, or has expired its service life. Check the connections or replace the sensor cartridge if it has passed its operational lifespan.

• How do I charge my portable Hanwei smart sensors?

  Many modern Hanwei portable sensors, such as the SKINDR400 and Mini600, are equipped with a standard Type-C charging interface. Use the provided USB-C cable to recharge the devices.
