This two cell water vapor transmission rate (WVTR) testing system is ideal for testing flat films, finished packages and components. It consists of 3 separate master instruments which can be expanded up to 9 satellite units, providing a total of 20 cells. These instruments offer our widest sensor range for WVTR testing. Complies with ASTM F-1249, TAPPI T557, JIS K-7129 and 21 CFR Part 11.
