The new Automatic Gravimetric WVTR Tester Gintronic Gravitest 6250 makes WVTR measurements of low perm materials 2-3 times faster than the previous generation systems. The maximum load of the new 0.01mg balance is an enormous 250g. This wide measuring range allows for the coverage of all of the existing applications in WVTR measurement. This includes wet cup, inverted cup, and dry cup, measurements with or without wax or mechanical sealing. The GraviTest 6250-50 can accommodate samples as thick as 50mm. Both models fully comply with EN ISO 12572, EN 1931, ASTM E96, ISO 2528 and many other Test Methods.
