Air Gas Detector Model
A gas detector is a device that converts a certain gas volume fraction into an electrical signal. It is also known as a gas sensor, gas transmitter, and gas monitor.
The gas detector sensor can measure carbon monoxide (CO), carbon dioxide (CO2), industrial wall-mounted carbon dioxide (CO2), oxygen (O2), ozone (O3), sulfur hexafluoride (SF6), hydrogen sulfide (H2S), ammonia (NH3), sulfur dioxide (SO2), nitrogen dioxide (NO2), total volatile organic compound (TVOC), phosphine (PH3), hydrogen (H2), methane (CH4), formaldehyde (HCHO), and other gases.
