JH-D gas detection alarm (hereinafter referred to as the alarm) is an industrial non explosion proof single circuit wall mounted gas detector developed by our company. When there is a gas leak in the air, the alarm displays the concentration value of the gas in real time. When the concentration of gas on site exceeds the set alarm value, the alarm immediately emits sound and light alarm signals and outputs switch signals, which can be linked to external equipment such as sound and light alarms, opening exhaust, closing valves, etc.

Features
4.3-inch high-definition color screen display, displaying real-time concentration, alarm, time, storage and other information; The menu interface displays the function names of each menu in full Chinese;
Adopting imported gas sensors combined with advanced sensor digital processing systems, it has high measurement accuracy, good stability, strong resistance to poisoning and interference;
Plug in sensor process design, by connecting different sensor components, can achieve detection of different gas objects, easy on-site inspection, and convenient maintenance in the later stage;
Simultaneously supporting RS485 and 4-20mA communication methods, with stronger compatibility; The detector has automatic identification and display functions for over concentration, sensor short circuit, and open circuit faults;
Intelligent digital sensor component technology, with good stability and strong anti-interference ability;
Infrared remote control design allows for on-site calibration of the alarm without the need for unboxing; Built in 1 set of passive switch output, and can also be connected to an external sound and light alarm to expand the sound and light alarm function.
