Water vapor permeability tester W203

water vapor transmission rateLEDfor textiles

Water Vapor Permeability Tester Electrolytic Sensor Method W203 Watef Vapor Permeability Tester Wholly automatic, software easy to use. Curves of transmission rate, water vapor density, humidity and température, auto record and continuous display. GBPI Water Vapor Permeability Analyzer W203 Working principle W203 Water Vapor Permeability Tester Adopt Electrolytic détection sensor method. 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 molécules 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 W203 Water Vapor Perméation Tester Features 1. Wholly automatic, software easy to use. Curves of transmission rate, water vapor density, humidity and température, auto record and continuous display. Can easily monitor interaction of parameters and the whole testing process. 2. Highly modularized. Setting, testing, baseline, calibration, report etc are independent. Powerful data analysis. Easy to operate. 3. Built-in computer, can work without external computer. 4. Température control: International advanced electromagnetic technology, program controlled, no need of external accessories. Précision 0.1°C. 5. Humidity control: Dual gas flow method, with broad range, high précision and stable flow. 6. Standard gas calibration and standard film calibration. 7. Auto judgment and auto stop. 8. Leakage protection; over range protection; auto save data when power is eut off; incorrect operation warning.
