Electrolytic Detection Method Water Vapor Permeability Tester
This apparatus is professionally used for deciding water vapor transmission rate of composite films, plastic films, back-sheets, high barrier materials, sheeting, waterproof materials, aluminum foils, and other things utilized in medical and sanitary industry. By examining the water vapor transmission rate, the practical indexes of materials could be controlled to cater to the necessities for production.
Principle
Below a convinced test temperature, a continuous humidity change is produced amid two sides of the test example. The water vapor infuses via the example into the dry side and at that time is taken to the detector, where relative electric signs will be made. The water vapor transmission degree and other limits can be got by examining and scheming these electrical indications.
