The industrial and commercial point type combustible gas detector is an intelligent detector developed by our company that can simultaneously output 4-20mA current signals and RS485 signals and display them in real time.
This product has the characteristics of high stability, high accuracy, and high intelligence, and is suitable for places where flammable gases exist, displaying the concentration value of flammable gases in real time. When the concentration of combustible gas on site exceeds the set alarm value, the detector outputs a switch signal to control external linkage equipment such as sound and light alarm, exhaust, solenoid valve, etc.
