    Product Overview:

    The JH-HW point-type combustible gas detector with a measuring range of 0 to 100% LEL (hereinafter referred to as the detector) is a smart detector developed by our company that can simultaneously output 4-20 mA current signals and RS485 signals and display them 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 on-site flammable gas exceeds the set alarm value, the detector outputs an on-off signal, which can be linked with external equipment: such as sound and light alarm, exhaust ventilation, valve closing, etc.
    Product Features:
    (1) OLED Chinese liquid crystal display;

    (2) Using imported infrared sensors combined with advanced sensor digital processing system, high measurement accuracy, good stability, strong anti-interference ability and long service life;
    (3) Support RS485 and 4-20mA communication mode at the same time, with stronger compatibility;
    (4) The detector has the function of automatic identification and display of over-concentration, short-circuit and open-circuit faults;
    (5) Plug-in sensor technology design, through matching different sensor components, different gas objects can be detected;
    (6) No calibration is required to replace the sensor. Intelligent digital sensor component technology has good stability and strong anti-interference ability;
    (7) Infrared remote control design, which can complete the adjustment operation of the detector without opening the cover on site, and has a top open cover wiring design;
    (8) Built-in a set of passive switch output, and can be connected to external sound and light alarms to expand the sound and light alarm function.
    (9) Built-in isolation chip, effectively reducing the paralysis of the entire system due to failure.
