Oxygen Transmission Rate Test System

C201B Oxygen Transmission Rate Test System is designed and manufactured based on the coulometric sensor method and conforms to ASTM D3985. This instrument can be used to measure the oxygen transmission rate of barrier materials with high and medium barrier properties with high accuracy and high efficiency. C201B is applicable to the determination of oxygen permeability of plastic films, sheeting, paper, and other packaging materials used in food, pharmaceutical, medical apparatus, consumer products, photovoltaic and electronic industries, etc.

• Reference film is provided for quick calibration
• The system adopts single-chip microcomputer control and can run independently
• The test report can be exported in common formats such as EXCEL and PDF
• Support micro printer, automatically print test data (optional)
• Equipped with RS232 data interface, which can be connected to computer software for curve analysis, data storage, report printing, etc. (optional)
• The gas purifier independently developed by Labthink can remove trace oxygen in nitrogen and provide oxygen-free carrier gas (optional).

 

Test Principle

The pre-conditioned specimen is clamped in the test cell, oxygen or air flows on one side of the specimen while a stream of high purity nitrogen flows on the other side. Oxygen molecules permeate through the specimen into the nitrogen side and are carried to the coulometric sensor. The sensor analyzes the oxygen concentration and calculates the oxygen transmission rate.
