Overview
Enviro Testers hydrogen gas detector is a fixed type of detector that can continuously monitor four gases in operation at the same time, that is, flammable gas, oxygen, carbon monoxide, hydrogen sulfide gas concentration. The detector uses natural diffusion to detect gas concentration. It uses imported electrochemical sensors, catalytic combustion sensors, infrared sensors or PID sensors. It has excellent sensitivity and excellent repeatability. The LCD liquid crystal suitable for factory applications displays the concentration of leaked gas. Start the sound and light alarm signal or drive the exhaust system immediately when the preset alarm point is exceeded. The international standard digital signal interface can be connected to the factory computer software. The detector uses embedded micro-control technology. The machine’s performance ranks in the domestic leading level, this product is suitable for petroleum, chemical industry, fire protection and other places that need to detect gas concentration.
