Water Vapor Transmission Rate Test System

Water Vapor Transmission Rate Test System is based on the cup method, and is professionally applicable to the water vapor transmission rate test of film specimens. It is equipped with high resolution sensor, whose test resolution is 0.0001g. The sensor also provides excellent test sensitivity.

Water Vapor Transmission Rate Test System is applicable to the determination of water vapor transmission rate of:
Basic Applications

Films

Including plastic films, plastic composite films, paper-plastic composite films, geomembranes coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others

Sheeting

Including engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC

Paper and Paper Board

Including paper and paper board, e.g. aluminum foil paper for cigarette packages and materials

Textiles and Nonwovens

  • Including textiles and non-woven materials, e.g. waterproof breathable fabric, non-woven fabric for diapers and hygienic products

  • Wide range and high-precision of automatic temperature and humidity control to support various combinations of non-standard test conditions

  • Standard air velocity enables constant humidity difference between two sides of test dishes

  • Automatic reset before weighing ensures accurate weighing data

  • Gas cylinder lifting structure design and periodically weighing method to reduce system errors

  • Convenient fast-access calibration ports for temperature and humidity
