Wall mounted oxygen monitorWidely used for monitoring and controlling environmental oxygen content in hotels, inns, hospitals, schools, laboratories, storage rooms, and other environments in high-altitude areas.
Main features of wall mounted oxygen monitoring instrument:
1) Friendly human-machine dialogue menu, intuitive and convenient operation;
2) Integrated design, small size, light weight, and simple structure ;
3) The sensor does not consume electricity, has a long service life, and is easy to maintain;
4) Compared with the principles of electrochemistry and ultrasound, it has a longer service life and faster response speed;
5) While monitoring changes in environmental oxygen, regulate the concentration of environmental oxygen to achieve optimal human adaptation to the environment;
6) The oxygen outlet is equipped with a muffler, resulting in low overall noise and meeting the noise requirements for sleep;
7) No reference gas required, unaffected by the oxygen concentration in the working environment;
8) Long calibration interval, high accuracy, stable and reliable;
9) High precision temperature automatic compensation system to eliminate the influence of environmental temperature;
10) Modular design allows users to freely add features .
