gas, oxygen, poisonous and harmful gases
QB300N series gas detector is a fixed type instrument that can continuously detect the concentration of gas, oxygen, toxic and hazardous gases in the working environment. The detector detects the gas concentration by natural diffusion, adopts high-quality electrochemical sensing with good sensitivity and excellent repeatability; the LED digital display suitable for factory application shows the concentration value of the leaking gas in real time, and the sound and light alarm or driving exhaust system is activated immediately after exceeding the preset alarm point; the international standard (4～20)mA signal can be directly connected to the factory DCS system, and the RS485 digital signal can be connected to the factory upper computer; the instrument is connected to the factory upper computer; and the instrument is connected to the factory upper computer; the instrument is connected to the factory upper computer. The instrument adopts embedded micro-control technology, simple operation and complete functions.
