Features

Integrated color digital module display;

Using imported electrochemical, infrared, photoionization, semiconductor and other sensors, combined with advanced digital sensor processing systems, the measurement accuracy is high, stability is good, and anti-interference performance is strong;

Plug-in sensor design: by connecting different sensor components, the unit can support different gas detection applications, enabling convenient on-site inspections and easy maintenance during later use. Simultaneously supports RS485 and 4–20 mA communication, offering stronger compatibility;

The detector features automatic identification and display for over-concentration, sensor short-circuit, and open-circuit fault conditions;

Sensing components are equipped with built-in storage calibration data and intelligent digital sensor component technology, providing good stability and strong anti-interference performance;

Infrared remote design enables on-site calibration and configuration of the detector without opening the cover;

Built-in 2 sets of passive switch output.
