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 detector);
4) High performance LED display
With digital tube concentration display and status indication function, it can real time display of gas concentration;
5) Adopting single-chip computer technology and highly sensitive anti poisoning gas sensors
Can automatically adapt to changes in the environment, automatically compensate for sensor sensitivity attenuation, and maintain high alarm sensitivity;
6) Dual electrical interface
Flexible wiring reduces construction difficulty;
7) With dust explosion-proof certification, expand the application scope of small and medium-sized plants
