1.High precise coulometric sensor.
2.One independent test chamber can test one sample for each test.
3.The stability of the temperature ensures the consistency of test conditions of chambers(optional).
4.High-precise and automatic control system of temperature can be used under different conditions.
5.The data can be stored and outputted in multi-format (including reports in excel and cloud sharing).
6.GMP management of user's three-level authority complies with international standards.
7.The instrument processes statistical analysis of single and group data.
8.Equipped with ISP control online and upgrade function.
9.Specialized communicating software can display in real-time, analyze and store data.
Test Principle:
The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. One chamber contains oxygen or air and the other chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing and calculating the signals. For package samples, high purity nitrogen flows inside the package, and oxygen or air flows outside.
