Water Vaper Permeability Tester Test Machine ISO 2528 ASTM E96 ASTM D1653


This instrument is based on the cup method, which is professionally applicable to the water vapor transmission rate test of thin film specimens. Through the determination of water vapor transmittance to control and adjust the technical index of material, meet the different needs of application.


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

Six distinct or equivalent specimens can be tested individually with independent test results at one operation.

Standard air velocity can effectively prevent the formation of moisture gradient.

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

Convenient fast-access calibration ports for temperature and humidity.

The system is controlled by computer and test process is automatic.

The tast report could be saved and provided in multiple formats,including Excel, database,etc.

Reference film or standard weight for fast and accurate calibration

The instrument is equipped with USB port and Common data port for convenient input, output, and data transfer

Applications Specifications

Basic   Applications


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


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

Paper and PaperBoard

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

Textiles and Nonwovens

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


Extended   Applications

Inverted Cup Method

Mount film or sheeting in test dish, cover   upper surface of specimen with distilled water, and make the lower side in   certain humidity. Generate a constant humidity difference between two sides;   water vapor permeates through specimen and measure weight changes in   different time to obtain the water vapor transmission rate.
  NOTE: inverted cups are required

Artificial Skin

Artificial skin has to meet standard   requirements for water vapor transmission rate to ensure better breath   performance. This instrument can be used to test  water vapor   permeability of artificial skin

 Medical Products and Accessories

Including plasters, aseptic wound   protecting films, face masks and scar sticks

Solar Back-Sheets

Including solar back-sheets

LCD Monitor Films

Including LCD monitor films

Paint Films

Test water vapor permeability of various   sorts of paint films


Test water vapor permeability of cosmetics

 Biodegradable Films

Test water vapor permeability of various   sorts of biodegradable films, e.g. starch-based packaging films
