Water Vapor Permeability Tester WVTR-C3
WVTR-C3 is based on the weighing method and available for the water vapor permeability
test of plastic films, aluminum foil, aluminized films, plastic composite films and many others.
(1) Weighing method
(2) Own technology
(3) 3 specimens, continuously test
(4) One-button test, test automatically in whole process
(5) Multiple test modes optional
(6) Temperature and humidity auto control
(7) Data curves display
(8) Computer control
(9) Environment temperature and humidity sensor inside
(10) Unit based on embedded system,24bit Δ-Σ AD
(11) Traceable reference film calibration
(12) Supports DSM system (DSM, lab data management system)
Test dishes filled with distilled water in a controlled dry atmosphere, a constant humidity
difference is generated between two sides of the test specimen, the water vapor permeates
through the specimen and into the dry side, water vapor transmission rate and other
parameters can be obtained by measuring the weight changes of the test dish in different
Mainframe, computer, W-CTrans software, test dishes(3),
desiccant tube, pressure regulator, automatic moisture filter, calibration weight,
communication cable, sample cutter.
Reference film, air drying device, sample cutter, DSM system.
