Water Vapour Transmission Rate Tester for Food Packaging

Cup-type or sensor instrument for water vapour transmission rate of films, used by biscuit, cereal and snack packers to decide pack barrier needs. Runs at controlled temperature and humidity chamber conditions.

Specification

A film seals a cup with desiccant or water, and weight change or sensor response is followed over time. Calculated WVTR in g/m2/day describes moisture barrier. Controlled chamber conditions keep results consistent.

Features

• Chamber 38 deg C, 90 % RH
• Multiple cup positions
• Infrared sensor option
• Automated reading
• Gravimetric method compatible
