  • Measurement cell (∅70mm, 30mm)
  • The Gas Permeability Tester measures gas transmission rate (gas barrier property) of packaging materials such as plastic films.
  • Measurement of gas transmission rate of polymer films such as plastic films, etc. is important because, for example in case of packaging materials, preservation of the content of a package considerably depends on the gas barrier property of the packing material.
  • Recently gas transmission rate measurement is being used in new fields such as functional polymer films.

Features

  • An automatic valve is used to realize fully automatic measurement. (No need for conventional manual valve operation)
  • Many kinds of gases can be measured. (Differential pressure method)
  • Additional expansion is possible by modular design.
  • Since measurement is performed while data is stored, data can be analyzed even during testing.
  • Mail transmission function allows you to receive a message when an error occurs or the test ends.
  • Allows analysis of diffusion coefficient and solubility coefficient (Optional)
  • High sensitivity vacuum pressure gauge of reading accuracy 0.25% is employed.
  • Specimen table supports two different sizes of specimen.
  • Performs temperature error correction of transmission gas.
