Water Vapor Transmission Rate (WVTR or MVTR)

W-061 Water Vaper Permeability Tester

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.

Professional Technology

-  Gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of the specimen could be obtained at one operation

Features

-  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.
