OX2/230 Oxygen Transmission Rate Test System

Professional, High Efficiency and Intelligent OTR System

Professional

This instrument is professionally designed for the determination of oxygen transmission rate test of film and package specimens. It has three test modes and is applicable to various materials with high, medium and low oxygen permeability. It is also embedded with high precision oxygen sensor, which provides a huge test range of 0.01~65000cm³/m²·d and durable service life.

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

World leading pressure compensation technology ensures accurate and repeatable test results

Standard, proportional and continuous testing modes facilitate to minimize errors caused by human factors during the testing process

Equipped with catalyst deaerator to purify carrier gas and reduce system errors

2 types of carrier gases are available: High purity nitrogen gas or hydrogen-mixed nitrogen gas

Convenient fast-access calibration port for temperature and humidity

Reference film for accurate calibration

High Efficiency

OX2/230 system is based on the equal pressure method and adopts Labthink’s latest exclusive patent design of three diffusion cells integrated in one instrument for individual or multiple tests, which improves test efficiency by 3 times. It can be easily connected with 9 satellite bases together to accomplish up to 30 tests at the same time.

3 diffusion cells integrated in one instrument with lower space occupancy rate and higher test efficiency

3 distinct or equivalent specimens can be tested individually with independent test results at one operation

The system can be easily connected with a maximum of 10 satellite bases to accomplish up to 30 tests at the same time

Oxygen transmission rate and water vapor 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

Save test data in different formats for convenient data transfer

Intelligent historical data searching, comparison, analysis and printing functions

Support Lystem™ Lab Data Sharing System for uniform management of test results and test reports

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 it produces corresponding amount of electrical signals. The oxygen transmission rate is then obtained by analyzing and calculating the signals. For package samples, high purity nitrogen flows inside the package, where oxygen or air flows outside
This test instrument conforms to the following standards:
ISO 15105-2, GB/T 19789, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, JIS K7126-B, YBB00082003

Applications

This instrument is applicable to the determination of oxygen transmission rate of:

Basic Applications	Films Including plastic films, plastic composite films, paper-plastic composite films, geomembranes coextruded films, aluminized films, aluminum foil, aluminum composite films, and many others
	Sheeting Including various sorts of engineering plastics, rubber, and building materials, e.g. PP, PVC and PVDC
