Laboratory embedded oxygen monitor has a friendly man-machine dialogue menu, which is intuitive and convenient to operate, The calibration interval is long, high precision, stable and reliable.
Laboratory embedded oxygen monitor main features:
1) Modular design, the user can choose the altitude measurement module;
2) Compared with electrochemical and ultrasonic, it has a long service life and fast response;
3) The sensor is not powered, does not consume, has a long service life and is easy to maintain;
4) no reference gas is required, independent of the operating environment oxygen concentration;
5) High-precision temperature automatic compensation system to eliminate the influence of ambient temperature;
6) The measurement range is 0 ~ 40.0% O2 wide.
