Oxygen Transmission Rate Tester for Composite Barrier Films

Coulometric OTR analyser for high barrier laminates, measuring oxygen permeation in cc/m2.day. Used in food, pharma and electronics packaging film development. It helps verify that films protect oxygen-sensitive food and pharma contents.

Specification

The film divides a cell into a test gas side with oxygen and a carrier gas side with nitrogen. A coulometric sensor measures oxygen reaching the carrier stream giving direct transmission rates down to 0.005 cc.

Features

• Coulometric sensor
• Range 0.005 to 100 cc/m2.day
• Temperature 10 to 50 deg C
• Humidity control option
• Multiple test cells
