Oxygen Transmission Rate Tester By Labthink International,inc.

Being a quality-centric organization, we are involved in offering superior quality Oxygen Transmission Rate Testing for Packages and Films at affordable rates. 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.

Salient Features:-
a c Wide range and high precision of temperature and humidity control, adding humidity to two sides of the specimen, to support various combinations of non-standard test conditions
a c World leading pressure compensation technology ensures accurate and repeatable test results
a c 3 diffusion cells are integrated in one instrument with lower space occupancy rate and higher test efficiency
a c 3 distinct or equivalent specimens can be tested individually with independent test results at one operation

Standards:-
This test instrument conforms to the following standards:
ISO 15105-2, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, GB/T 19789, JIS K7126-2, YBB00082003
