Ion current oxygen monitor 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 electrochemical and ultrasonic, it has a long service life and fast response.
Ion current oxygen monitor main features:
1.Integrated design, small size;
2.Modular design, The user can select an altitude measurement module;
3.No reference gas is required, and is not affected by the working environment oxygen concentration;
4.The calibration interval is long, high precision, stable and reliable;
5.High-precision temperature automatic compensation system to eliminate the influence of ambient temperature;
6.The measurement range is 0 ~ 40.0% O2 wide.
