C390M Water Vapor Transmission Rate Test System is newly designed and upgraded on W3/230 Infrared Sensor Method Water Vapor Transmission Rate Tester. Compared with W3/230, C390M is upgraded with 1. Adope Labthink’s second generation patent design of three diffusion cells integrated in one instrument, which improves the test resolution, repeatability and performance in temperature and humidity control. 2. equipped with newly designed humidity control device, which can guarantee more accurate and stable test humidity in testing process 3. Patent design of core optic parts, resolution of the sensor reaches ppb level. 4. High performance signal processing unit can detect the signal for the concentration of water vapor accurately and quickly. Referring Test Standards ISO 15106-2, ASTM F1249, GB/T 26253-2010, TAPPI T557, JIS K7129, YBB 00092003-2015 Test Parameters -- Test range: 0.05 ~ 40 g/(m2·d) -- Resolution: 0.001 g/(m2·d) - Repeatability:Bigger one of ±0.05 and 2% g/(m2·d)
