Principle and Standards

Principle

The pre-conditioned specimen is mounted between the lower and upper chambers at ambient atmospheric pressure. One chamber comprises of air or oxygen and the other chamber is slowly purged by a stream of nitrogen. Oxygen molecules permeate through the specimen into the nitrogen side due to the concentration difference between the two chambers. These molecules are taken to the coulometric sensor where proportional electrical signals are produced. The oxygen transmission rate is then attained by examining and calculating the signals. High purity nitrogen flows inside the package, and air or oxygen flows outside for package samples.

Standards

This test instrument conforms to the following standards:

ISO 15105-2, ASTM F2622, ASTM F1307, ASTM F1927, ASTM D3985, JIS K7126-2, GB/T 19789, YBB00082003

High Efficiency

OX2/230 system is based on the equal pressure method and adopts Labthink’s most recent exclusive patent design of three diffusion cells incorporated in a single instrument for multiple or individual tests, which enhances test efficiency by three times. It can be effortlessly connected with nine satellite bases together in order to accomplish up to 30 tests simultaneously.

  • Three diffusion cells are incorporated in a single instrument with lower space occupancy rate and greater test efficiency
  • Three equivalent or distinct specimens can be tested separately with separate test results at one operation
  • The system can be effortlessly connected with a maximum of 10 instruments in order to accomplish up to 30 tests simultaneously
  • Water vapor transmission rate and oxygen transmission rate can be obtained at one operation by working with Labthink’s water vapor transmission rate test system together under the control of one computer
