Water Vapor Permeability Testers

Water vapor permeability tester is based on the cup method, and is professionally applicable to the water vapor transmission rate test of plastic films, composite films, sheets and other materials used in medical and construction industry. By testing the water vapor transmission rate, the technical index of the materials could be controlled to meet the requirements for production.

Applications of water vapor permeability tester:
is applicable to the determination of water vapor transmission rate of:
1.Films
2.Sheeting
3.Paper and Paper Board
4.Textiles and Nonwovens

Features of water vapor permeability tester:-
1. Standard periodically weighing method and auto zero before each weighing guarantee the accuracy and uniformity of the testing data
2. Three specimens could be tested simultaneously and the test dishes are lifted and lowered by the gas cylinder which ensures the reliability of the test
3. Standard air velocity to prevent the humidity difference spread which ensures the accuracy of the test
4. Wide range and high-precision of automatic temperature and humidity control to support various combinations of non-standard test conditions
5. Universal RS232 communication port is convenient to the data export and transmission
