Foil Water Vapour and Gas Barrier Permeability Tester

Permeation tester for barrier properties of foil laminates, measuring moisture transmission through pinholes and flex-cracks. Used in blister pack and sachet foils. It also shows how flex-cracking and defects raise moisture ingress.

Specification

The foil sample divides two chambers, one with humid air and the other with dry carrier gas. An infrared sensor detects water vapour crossing and reports g/m2 per day.

Features

• Infrared moisture sensor
• Temperature 10 to 55 deg C
• Humidity 10 to 90% RH
• Two test cells
• Auto calibration with reference film
