Oxygen Transmission Rate Test System - C230M

The C230M Oxygen Transmission Rate Test System is manufactured and designed based on the coulometric sensor method (aka. equal pressure method). It conforms to ASTM D3985, ASTM F2622 and ISO 15105-2.

It is an instrument that can be used to measure the oxygen transmission rate of barrier materials with high, and medium barrier properties with high accuracy and high efficiency.

The C230M Oxygen Transmission Rate Test System features Labthink’s patented design of integrated test block made up of three permeation cells. Provided with a high precision coulometric sensor and Labthink’s professional computer-controlled system, it has the ability to control and regulate the temperature, humidity and flow rate precisely, this guarantees high sensitivity and excellent repeatability of test results.

C230M applies to the determination of oxygen permeability of plastic films, paper, sheeting and other packaging materials used in food, medical, pharmaceutical apparatus, consumer products, photovoltaic and electronic industries, etc. Optional accessories allow for the testing of complete packages and systems such as bottles, cartons, pouches, blister packs, tubes and more.
