 
            
1) Beautiful and compact design
Small design, Small size, more space saving;
2) Modular design
The sensor can be hot-swapped and replaced, reducing the follow-up maintenance cost of the product. Especially for electrochemical sensors with a short life, it can save users a lot of replacement costs;
3) Can be equipped with explosion-proof audible and visual alarm
It can be equipped with ACTION explosion-proof audible and visual alarm to meet the needs of users for audible and visual (especially for the detection of toxic gases);
4) High reliability digital tube display
With digital tube concentration display and status indication function, gas concentration and equipment operating status can be observed on site;
5) Selection of commonly used toxic and combustible gases
Solve the detection needs of most gas and small and medium-sized plants (CH4, C3H8 (propane), Co, H2S, NH3, SO2, O2, H2);
6) Fast response time and high sensitivity
7) With dust explosion-proof certification, expand the application scope of small and medium-sized plants
