PERME TSY-T3 Water Vapor Permeability Tester is applicable in water vapor permeability testing of plastic films, laminated films, high barrier materials, back sheets of solar panels, sheets, foils, building thermal insulation material and waterproof membrane, as well as various materials in medical field. The water vapor permeability measurement can meet the demands to control and adjust material technical indexes for product applications.
Characteristics
Computer control, automatic testing process;
12 independent chambers;
Interval weighing, auto zero before each weighing;
Cylinder cam type lifter lift and lower the cups;
Standard wind speed;
Automatic temperature control;
Automatic humidity control;
Temperature and humidity calibrate port;
Specified function matching;
Two calibration modes of reference weight and reference film;
RS232 interface;
Network transmission interface for LAN data management and Internet data transmission.
Principle
Under a certain temperature, form a certain humidity pressure between the two sides of
specimen, water vapor transmits the specimen and enter the dryer side. Determine the water vapor transmission rate and transmission coefficient by measuring the decreasing weight of distilled water with time going.
Performance
Max. 12 different materials can be tested simultaneously, various test modes selectable;
Through computer processing, data can be statistically analyzed and stored in categories. When inquiring historic testing data, the historic data of a specimen category and their dynamic analysis drawing are obtainable. Thus, achieving thorough analysis of testing process.
