Product Profile • The W416 2.0 Infrared Method Water Vapor Transmission Rate Tester is a high-end precision testing instrument for packaging materials, newly developed and upgraded by Guangzhou Standard International R&D Team in full compliance with the requirements of **GB/T 26253** and **ASTM F1249** standards as well as market demands. • Based on the testing principle of infrared moisture analysis sensors, it provides wide-range, high-efficiency water vapor transmission rate (WVTR) testing for high, medium and low barrier materials. • It is suitable for testing the water vapor transmission performance of films, sheets, papers, packages and other related materials in industries such as food, pharmaceuticals, medical devices, daily chemicals, photovoltaic electronics, etc. • It is an ideal offline or online configuration instrument for manufacturers in the packaging industry to test the barrier performance of packaging materials. Testing Principle The W416 2.0 Water Vapor Transmission Rate Tester adopts the infrared method principle: 1. Fix the pre-treated sample in the middle of the test chamber, dividing the chamber into a high-humidity chamber and a low-humidity chamber. 2. Compressed air flows through the high-humidity chamber, while dry nitrogen (carrier gas) flows through the low-humidity chamber at a constant flow rate. 3. Due to the humidity gradient, water vapor penetrates from the high-humidity chamber to the low-humidity chamber. 4. The water vapor passing through the sample is carried to the infrared sensor by the flowing dry nitrogen. 5. Parameters such as the sample’s water vapor transmission rate are derived from the electrical signal output by the sensor.
