Laboratory embedded oxygen monitor

모델명 :

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.
