Water vapor transmission rate tester W416 2.0

sensorfor pharmaceutical applicationsfor the electronics industry

Product Introduction
W416 2.0 Infrared Water Vapor Transmission Rate Tester is an upgraded high-precision instrument developed according to GB/T 26253, ASTM F1249 and related international standards. Based on patented infrared moisture sensor technology, it delivers wide-range WVTR measurement for high-, medium- and low-barrier materials. Applicable to films, sheets, paper, packaging and materials used in food, pharmaceutical, medical device, personal care, photovoltaic and electronics sectors; suitable for offline and online packaging testing.

Test Principle
The sample is clamped in the test chamber, creating wet and dry sides. Compressed air is introduced to the wet side while dry nitrogen (carrier gas) flows through the dry side at a controlled rate. Water vapor migrates across the sample into the dry chamber and is carried to the infrared sensor. WVTR is calculated from the sensor's electrical output.
