The i-Hydro 7300 Water Vapor Transmission Rate Tester

Labthink’s i-Hydro 7300 water vapor transmission rate tester, operated on gravimetric method, is used for testing water vapor transmission rate of sheeting, building materials, composite films, pharmaceutical materials and plastic films.

The design based on Water Method complies with all standards of testing. The tester has standard air velocity which enhances the testing accuracy.

Key Features

The major features of the i-Hydro 7300 water vapor transmission rate tester include:

  • Fast-access calibration port for measurement of humidity and temperature
  • Automatic humidity and temperature control system
  • Standard weight or reference film which ensures accurate and rapid calibration
  • Individual weighing mechanism for three samples
  • Dual Internet ports and four USB ports
  • Gas cylinder controlled mechanism for raising and lowering the test dishes during test operations
  • Standard weight or reference film for fast and precise calibration

Basic Applications

  • Films: Including plastic films, plastic composite films, paper-plastic composite films, geomembranes, coextruded films, aluminized films, aluminum foils, aluminum composite films, breathable water-proof films and many other film materials
  • Sheeting: Including engineering plastics, rubber, waterproof building materials, and thermal insulation materials, e.g. PP, PVC, PVDC, and nylon
  • Paper and Paper Board: Including paper and paper board
  • Textiles and Nonwovens: Including textiles and non-woven materials
  • Aseptic Wound Protection Films and Face Masks: Including aseptic wound protecting films, face masks, and protection clothing materials

Extended Applications (Additional Accessories Required)

  • 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 cup required
  • Solar Back-sheets: Including solar back-sheets and OLED packaging materials
  • LCD Monitor Films: Including LCD monitor films
