GINTRONIC AG showed their very successful development in the field of permeation measurements. The company presented GraviTest Model 6300 to the growing demand of simple, reliable and economic water vapour transmission rate testers.  GraviTest  fulfils the conditions for EN ISO 13859 standard for roofing underlayers.

GraviTest is a completely automated, gravimetric water vapour transmission rate tester that is able to determine the water vapour transmission rate simultaneously on 6 samples. Re-sealable specimen holders with an integrated seal make wax-sealing of the samples redundant.

The user-friendly PC software in combination with the accurate and robust balance allows high precision gravimetric measurement of water vapour permeability in the shortest possible time.

GraviTest conforms to the most important international standards: ASTM E96, ISO 2528, EN ISO 12572, EN1931, BS 3177, DIN 52615, DIN 53122 Part 01 and others.
