Water vapor permeability tester W416 2.0

WVTRmoisturesensor

Product Introduction
The W416 2.0 Water Vapor Transmission Rate Tester is a precision WVTR instrument developed by GBPI R&D to meet GB/T 26253, ASTM F1249 and related international standards. Using a patented infrared moisture sensor, it delivers wide-range WVTR measurement for high-, medium- and low-barrier materials in laboratory and production environments.

Test Principle
The sample is mounted between wet and dry chambers. Compressed air is supplied to the wet side while dry nitrogen (carrier gas) flows on the dry side at a controlled rate. Water vapor diffuses through the sample into the dry chamber and is detected by the infrared sensor; the WVTR is calculated from the sensor's electrical output.
