Water Vapour Permeability Analyzer is applicable in water vapour permeability test of barrier materials such as plastic film and laminated film. Users can control and adjust the technical index of packaging materials by testing the water vapour transmission rate.
Characteristics:

  • Cup method
  • High in efficiency
  • 12 test chambers test at same time or test in random groups
  • Satisfies different test conditions
  • Controlled automatically
  • Transmission and weigh up are in same ambient
  • Little errors caused by human operation
  • Highly accurate sensor
  • Data reliable
  • Flexible heating equipment, even and gentleness
  • P.I.D. system controls temperature accurately
  • Little temperature fluctuation
  • Professional software,test data displayed dynamically
  • Database mode storage
  • Easy to analyze
  • Functions of storage, researching, printing, plotting, and communication
  • Computer controls automatically
  • Easy to operate
  • Friendly human-equipment interact

Principle:
  • Saturated water vapour transmits through specimen in a unit time under specified conditions of temperature and humidity.
  • Determine the transmitted mass by test the decreasing weight of distilled water with time going.

Performance characteristics:
  • Before test, just input parameters of pre-heating time, test temperature, and so on.
  • Tester will finish the test automatically and print out test results
  • WVTR under different conditions got, one group or multi-groups test conditions set according to actual requirement of packaging materials
  • The upper limit is that 12 different materials are tested at one time, selectable various test conditions
  • Computer enables the functions of storage, researching, printing, and curve displaying
  • Calibrate by standard poise, easy to operate
