상품상세정보

Trace oxygen analyzer adopt an unique protection air circuit which can protect the sensor efficiently and prevent the sensor from being exposed in the air for too long to affect its serving life. The imported fuel-cell oxygen sensor is with long serving life, a rapid response speed, high measurement accuracy and long calibration cycle for features, etc.

Trace oxygen analyzer main features:

1. Only one random point needs to be calibrated among the whole measurement range, and the measured accuracy among the whole measurement range can be met without multi-points calibration;

2. Function of built-in temperature compensation could eliminate the influence from the changes of environment • temperature on the measured accuracy;

3. Function of storing data automatically makes looking through historical data at any time possible; 

4. Function of shifting Chinese-English menu makes the operation visual and easy;

5. Built-in imported extraction pump (optional).
