PERME TSY-W3 Electrolytic Detection Method Water Vapor Permeability Tester is applicable for water vapor permeability test of various packaging materials, including plastic films, laminated films, back sheet, high barrier materials, sheets, foils and waterproof membrane, as well as various high barrier materials in medical and pharmaceutical field. The water vapor permeability rate testing can control and adjust the technical indexes of materials, so as to meet application demands.
Characteristics
Micro-computer control; LCD display;
Manu interference, PVC operation board;
Constant temperature control;
Humidity control;
Optional finished package water vapor permeability rate testing;
Rapid calibration with reference film;
Mini-printer;
RS232 port;
Network transmission interface for LAN data management and Internet data transmission.
Principle
Place the specimen between the constant temperature dry and humid chambers, owing to the pressure differences, saturated water vapor will permeate through specimen from the high humidity chamber to the low humidity chamber and is then carried to the sensor, which would generate electrical signal at the same time. Through electronic signal analysis and calculation of the sensor, water vapor permeability rate and water vapor permeability coefficient can be obtained.
