W202 Water Vapor Permeability Analyzer Application
How to test packaging materials water vapor transmission rate (WVTR) and what function does water vapor permeability testers have? GBPI Supply Unique and Certificated Water Vapor Permeation Analyzer to test different packaging material WVTR such as plastic film, composite film, coextrusion film, aluminum-plated film, aluminum foil, infusion bag, sheets, paper, paper board, solar battery panel, cellophane, ceramics and porcelain, and various containers such as bag, pouch, bottle, can, bowl, box, widely used in the industries of food, pharmaceuticals, personal care, household, electronics and so on.
What is W202 water vapor permeability analyzer Working principle
GBPI W202 Water Vapor Permeability Tester use Electrolytic detection sensor to test packaging material WVTR.
Fix the test sample in the middle of test chamber to separate the chamber into upper room and lower room. When humid gas flows in upper room and dry gas in lower room, the water molecules in upper room penetrate through the sample into the dry gas, and electrolytic sensor system detect and analyze the water content and calculate the water vapor transmission rate.
