W401L Infrared Water Vapor Transmission Rate Tester High Precision WVTR Testing Instrument for Packaging & Barrier Materials Product Introduction W401L Infrared Water Vapor Transmission Rate Tester is an upgraded high-end precision testing instrument developed by GBPI R&D team in accordance with ASTM, GB and international standards. It measures water vapor transmission rate of samples under controlled temperature and humidity, widely used for films, sheets, paper, packages and materials in food, pharmaceutical, medical devices, daily chemical, photovoltaic and electronics industries. Get a Free Quote Today   Test Principle W401L adopts the infrared sensor testing principle. The pre-processed sample is fixed in the test chamber, dividing it into wet and dry sides. Compressed air flows in the wet chamber, and dry nitrogen (carrier gas) flows in the dry chamber at a fixed rate. Due to humidity gradient, water vapor permeates to the dry chamber and is carried to the infrared sensor. The WVTR value is calculated by the electrical signal output from the sensor.   Compliant Standards ISO 15106-2 ISO 21760-1 ASTM F1249 GB/T 26253 JIS K7129-2 Chinese Pharmacopoeia 4010 YBB 00092003   Technical Specifications Item Value Test Range 0.01~200 g/(m²·24h) Resolution 0.0001 g/(m²·24h) Temperature Range 15~45℃ Temperature Accuracy ±0.2℃ Humidity Range 5~90%RH, 100%RH Humidity Accuracy ±2%RH Test Area 50.24 cm² Sample Size Φ100 mm Test Chambers 1 channel   Key Features Patented high-precision infrared moisture sensor with ultra-high stability and 0.0001 g/(m²·24h) resolution.
