JH-TCQ – X toxic gas detector is an intelligent detector developed by our company that can simultaneously output 4-20mA current signal and RS485 signal and display them in real time.
This detector is mainly used in places with toxic and harmful gases, displaying the concentration value of the gas to be detected. When the concentration of a certain gas to be tested on site exceeds the set alarm value, the passive switch inside the detector will activate and control external linkage equipment such as sound and light alarm, exhaust, solenoid valve, etc.
