Oxygen Transmission Rate Tester for Food Packaging Films

Coulometric OTR tester that measures oxygen permeability of films and laminates in cc per square metre per day. Used by snack, dairy and meat packers to qualify barrier packaging structures.

Specification

A film is clamped between two chambers, with oxygen on one side and nitrogen carrier on the other. A coulometric sensor measures oxygen permeating through. Result is in cc/m2/day and indicates barrier quality.
