W416 2.0 Infrared Water Vapor Transmission Rate Tester High Precision WVTR Tester | 6 Independent Test Chambers Product Introduction W416 2.0 Infrared Water Vapor Transmission Rate Tester is an upgraded high-end precision testing instrument developed by GBPI R&D team in accordance with GB/T 26253, ASTM F1249 and international standards. Based on infrared moisture sensor technology, it provides wide-range and high-efficiency WVTR test for high, medium and low barrier materials. It is widely used for films, sheets, paper, packages and materials in food, pharmaceutical, medical devices, daily chemical, photovoltaic and electronics industries, ideal for offline and online testing in packaging industry. Get a Free Quote Today   Test Principle W416 2.0 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 0.002~100 g/(m²·24h) Repeatability 0.005 or 2% (whichever is greater) Resolution 0.0001 g/(m²·24h) Temperature Range 15~45℃ Temperature Accuracy ±0.1℃ Humidity Range 5~90%RH, 100%RH Humidity Accuracy ±1%RH Test Area 50.24 cm² Sample Size Φ100 mm Sample Thickness ≤3 mm Test Chambers 6 channels (independent data)   Key Features Patented high-precision infrared moisture sensor, ultra-high stability, resolution up to 0.0001 g/(m²·24h).

Product Brief The N600C Carbon Paper Air Permeability Rate Tester is designed and developed in accordance with GB/T 20042.7-2014. Adopting the differential pressure method as its testing principle, it is professionally used for measuring the air permeability rate of various types of carbon paper for proton exchange membrane fuel cells (PEMFC). Testing Principle Based on the differential pressure method, the sample is placed between two fixtures, forming a constant differential pressure on both sides of the sample. Driven by the differential pressure, gas flows from the high-pressure side through the sample to the low-pressure side. The air permeability rate of the carbon paper is calculated based on the transmission flow rate, sample thickness, test area, and test differential pressure.
