Water Vapour Transmission Rate (WVTR) Tester for Solar Backsheet

The barrier efficiency of sloar backsheet should be tested using measuring devices with sensitive sensors which can detect even the tiniest amount of water. Usually, water vapor transmission rate tester which is used to test solar backsheet conforms to ASTM F1249. Labthink W3/330 water vapour transmission rate tester is right based on ASTM F1249 with high sensitive sensor. Features, 1. wide test range of 0.001~1000g/m2·24h and durable service life. 2. three diffusion cells integrated in one instrument for individual or multiple tests, which improves test efficiency by 3 times 3. Wide range and high precision of temperature and humidity control 4. Reference film for accurate calibration Specifications, 1. Resolution 0.001 g/m2·24h 2. Temperature Range 15°C~55°C (standard) 3. Temperature Accuracy ±0.1°C (standard) 4. Humidity Range 0%RH, 35%RH~90%RH, 100%RH 5. Humidity Accuracy ±1%RH
