Industrial and Commercial Use Point Type Combustible Gas Detector

GT-JH601 industrial and commercial point-type combustible gas detector (hereinafter referred to as detector) is an intelligent detector developed by our company that can output 4-20mA current signal and RS485 signal at the same time and display it in real time.
This product has the characteristics of high stability, high accuracy and high intelligence. It is suitable for places where flammable gas exists, and displays the concentration value of flammable gas in real time. When the concentration of combustible gas on site exceeds the set alarm value, the detector outputs switch signal, which can be linked with external equipment: such as sound and light alarm, open exhaust, close valve, etc.

(1) Digital module integrated display;

(2) Adopt imported anti-poisoning sensor, combined with advanced sensor digital processing system, high measurement accuracy, good stability, anti-poisoning, strong anti-interference ability;

(3) The plug-in sensor process design can realize the detection of different gas objects by matching different sensor components, which is convenient for on-site investigation and convenient maintenance in the later period;

(4) Support RS485 and 4~20mA communication modes at the same time, with stronger compatibility;

(5) The detector has automatic identification and display functions for over-concentration, sensor short-circuit and open-circuit faults;

(6) There is no need for calibration to replace the sensor, and the intelligent digital sensor component technology has good stability and strong anti-interference ability;

(7) Infrared remote control design, the adjustment operation of the detector can be completed without opening the cover on site, and the rear opening cover wiring design is adopted;

(8) Built-in 2 sets of passive switch output, and external sound and light alarm can be connected to expand the sound and light alarm function.
