PERMETM W3/060 Water Vapor Transmission Rate Test System is applicable for water vapor transmission rate test of plastic films, laminated films, sheets, high barrier materials, back sheet, foils, waterproof membrane and building thermal insulation materials, as well as varied materials in medical and pharmaceutical fields. Through water vapor transmission rate testing, control and adjustment of material technical can be achieved so as to meet product application demands.
Characteristics
Computer control, automatic testing process;
6 independent chambers;.
1 master base can support 9 satellite modules; 60 independent samples can be tested simultaneously;
Interval weighing, auto zero before each weighing;
Cylinder cam type lifter lift and lower the cups;
Standard gas flux;
Automatic temperature control;
Automatic humidity control;
Temperature and humidity testing port;
Test report can be stored in txt, data base and excel formats;
Broad power range;
Two rapid calibration modes of reference weight and reference film;
Network transmission interface for LAN data management and Internet data transmission.
Principle
A certain humidity difference is achieved between two sides of the specimen under certain pressure. Water vapor passes through the sample and enters the dry side. Obtain the water vapor transmission rate and other parameters by detecting and calculating the weight change of the cup with time going.
