Description
Overview
GAOTek multi-gas detector – automatic battery detection can detect the content of 4 gases (oxygen,carbon monoxide, hydrogen sulfide and methane) together. It will alarm immediately when the concentration of gas reaches or exceeds the preset alarm point.
Features
- Real-time detection of oxygen, carbon monoxide, hydrogen sulfide and methane
- True-color lattice TFT screen displays gas concentration
- Automatic battery detection and under-voltage indication.
- Alarm with LED, buzzer,earphone(optional) and vibration
- Brightness of back light can be set according to practical need to save power
- Storage of historical data and alarm events
- NDIR printer can print real-time concentration data(optional)
- Gas pump realizes detection by pumping(optional)
- Calibration and set of detector through PC
