Water Vapor Transmission Rate (WVTR) Measurement by AQUATRAN

Print

Summary

AQUATRAN is the valuable apparatus to evaluate water vapor transmission rate (WVTR) of ultra-high-barrier films for electronic devices which require the very high level of the water-free condition.

ANAC has developed the technology with AQUATRAN so that 10-4 level of WVTR cab be measured.
