1. Product Overview:
The GTYQ-JH600 type industrial and commercial point-type combustible gas detector (hereinafter referred to as the detector) is an intelligent detector developed by our company that can output RS485 signals and display them in real-time.
This product boasts high stability, accuracy, intelligence, and a long service life, suitable for environments with flammable gases. It displays the concentration of combustible gases in real-time. If the concentration of flammable gases on-site exceeds the set alarm level, the detector outputs a switch signal to control external interlocked equipment, such as sound and light alarms, exhaust fans, and solenoid valves.
2. Product Features:
Color digital module integrated display
(2) Utilizes imported anti-poisoning sensors, combined with an advanced digital processing sensor system, offering high measurement accuracy, excellent stability, resistance to poisoning, and strong anti-interference capabilities.
(3) The detector features automatic identification and display functions for over-concentration, sensor short-circuit, and open-circuit faults.
(4) Infrared remote control design allows for calibration and settings adjustment of the detector without opening the cover on-site.
(5) Built-in 1 set of passive switch quantity output, which can also be connected to an additional sound and light alarm to expand the sound and light alarm function.
