• Efficient test, low nitrogen consumption, can be tested and verified by national standard;
• Extensible container testing;
• The system has self-detection ability to avoid continuing testing under fault state;
• Gas flow monitoring, automatic alarm when there is little gas or no gas;

Test principle

The sample is installed between the sample gas and the carrier gas chamber, and the temperature of the test chamber is controlled. The oxygen of the sample gas chamber penetrates into the carrier gas chamber, and is carried by the carrier gas to the trace oxygen sensor. Precise measurement of trace oxygen sensors. The current is generated to calculate the oxygen transmission and other parameters of the sample.
