HT-G series gas detector (hereinafter referred to as detector) is a detector independently developed by our company, which can be widely used in petrochemical, fire protection, environmental protection, scientific research and other dangerous places where gas leakage is easy to leak indoors and outdoors.
HT-G series detector signal output mode is 4mA~20mA current signal, bus communication system (RS485) digital signal, switching quantity signal output, according to different models, it can be transmitted with the corresponding adapted control host, through the control host to display the gas concentration (×10-6 or %LEL) in real time, through the control host to set the detector high/low limit alarm value, calibrate, Realize all the actions of the monitoring detector, and provide you with humanized and operable services for safe production.
