Wall-mounted oxygen monitor has a friendly man-machine dialogue menu, which is intuitive and convenient to operate. The sensor is not powered, does not consume, has a long service life and is easy to maintain. Compared with the principle of electrochemistry and ultrasonic, the service life is long and the response speed is fast. Oxygen outlet is equipped with a silencer, low noise, to meets the noise requirements of sleep. The calibration interval is long, high precision, stable and reliable.
Wall-mounted oxygen monitor main features:
1) While monitoring environmental oxygen changes, the adjustment of the ambient oxygen concentration is realized to achieve the best adaptation of the human body;
2) With wireless transmission function, it can be remotely controlled for centralized management;
3) With remote control function, easy to operate;
4) no reference gas is required, and is not affected by the working environment oxygen concentration;
5) High-precision temperature automatic compensation system can eliminate the influence of ambient temperature;
6) Modular design, users can freely add features.
