Oxygen Permeability Tester - QT-OPT-201 is ideal for industrial application laboratory testing of material for Oxygen permeability testing for quality control, research and development on plastic, metal, paper and rubber materials that are generally used as packaging materials for storage, preservation or transportation of perishable and oxidizable materials.

It can also be used for research laboratories to evaluate and define permeability behaviour of material.

The built in software performs complicated data analysis and displays the relations in the form of graphs and data tables which significantly reduces the time to determine the permeability rate and relations between different output parameters of a variety of test subjects.

It is fully equipped with reliability, speed, versatility and accuracy required for Quality Control testing and laboratory application.

Working Principle

The specimen is mounted as a sealed semi-barrier between two chambers at ambient atmospheric pressure. One chamber is slowly purged by a stream of nitrogen act as a carrier gas and the other chamber is filled with oxygen at controlled pressure.

As oxygen gas permeates through the film into the nitrogen carrier gas, which is then passed through high precision coulometric detector where it allow an electrical current pass through detector, the magnitude of which is proportional to the amount of oxygen molecule flowing into the detector per unit time. Thus the permeation rate can be measured with very high accuracy

The state of the art automation technology delivers accurate performance with faster and real time test results. Its user friendly interface lets the new user adapt to the device faster.
