1 Product description:
Portable multi-gas alarm is a continuous detection of multi-gas (combustible gases, oxygen and toxic gases) concentration, easy to use personal protective gas detector. The color OLED display shows the measured gas concentration and other information. The decibel buzzer, alarm indicator and vibration alarm indicate that the current gas concentration has exceeded the set alarm point.
2 Features and benefits：
- The color OLED display continuously displays the gas concentration in real time
- Automatic zero adjustment and calibration function
- Automatically start full-function test (including sensor fault detection) when power on
- Gas concentration curve browsing function, intuitive and convenient (optional, factory settings)
- The screen display content can be flip over (optional, need to customize)
- Event record function (optional, to be customized)
- Detection of toxic gas types can be set (optional, to be customized)
- Sound, light, vibration 3 kinds of alarm
- Rechargeable lithium-ion polymer battery design
- Explosion-proof design
