Features

 

4.3-inch high-definition color screen display, showing real-time concentration, alarm status, time, storage, and other information; the menu interface displays the full names of each function in Chinese;

Adopts imported gas sensors combined with an advanced sensor digital processing system, delivering high measurement accuracy, good stability, and strong resistance to poisoning and interference;

Plug-in sensor design: by connecting different sensor modules, it can detect different gas targets, enabling easy on-site inspection and convenient later-stage maintenance;

Simultaneously supports RS485 and 4–20 mA communication methods for stronger compatibility. The detector features automatic identification and display functions for over-concentration, sensor short-circuit, and open-circuit faults;

Intelligent digital sensor module technology provides good stability and strong anti-interference capability;

IR remote control design enables on-site alarm calibration without unboxing. Built-in 1 set of passive switch output; it can also be connected to an external sound-and-light alarm to expand the sound-and-light alarm function.
