Water Vapor Transmission Rate (WVTR) Tester / Water Vapor Permeability Tester | 572-CT

The Water Vapor Transmission Rate (WVTR) Tester measures the water vapor permeability or water vapor permeability coefficient of packaging materials such as plastic film.

 

Measures water vapor permeability and water vapor permeability coefficient of plastic films, etc. using the differential pressure method.

 

ISO 15106-5 Plastics — Film and sheeting — Determination of water vapour transmission rate — Part 5: Pressure sensor method

 

Features & Benefits

● Measuring section supports two types of specimen sizes. (measuring section diameter ∅ 30 mm and ∅ 70 mm)

● Modularization of the measuring section allows for additional modules to be added.

● High-precision vacuum pressure gauge with a reading accuracy of 0.25.

● E-mail function allows messages to be received when an error occurs or a test is completed.
