OTR – Oxygen Transmission Rate Machine:

This instrument is used to determine the oxygen permeability of films used for packaging in the food and pharmaceutical industries. It tests plastic films, plastic composite films, and paper-plastic composite films. Moreover, it is also used for testing of Aluminized films, aluminum foil, aluminum composite films.

• Program controlled testing for easy control of test parameters to get accurate test results.
• It records the curves of the permeation rate, oxygen concentration, humidity, and temperature with real-time display to monitor.
• Equipped with functions of double cavity pressure control and automatic pressure balance.
