W3/330 Water Vapor Transmission Rate Test System
Introduction
The test specimen is mounted in the diffusion cell, which is subsequently divided into a dry chamber and a controlled-humidity chamber. The dry side of the specimen is swept by a flow of dry nitrogen, and the water vapor permeating through the specimen from the controlled-humidity chamber is carried by dry nitrogen to the electrolytic sensor where proportion electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For package samples, dry nitrogen flows inside the package, and moisturized nitrogen flows outside.
This test instrument conforms to the following standards: ISO 15106-3, GB/T 21529, DIN 53122-2, YBB00092003
Features
Wide range and high precision of temperature and humidity control to support various combinations of non-standard test conditions
Standard, proportional and continuous testing modes facilitate to minimize errors caused by human factor during testing process
Convenient fast-access calibration port for temperature and humidity
Reference film for accurate calibration
3 diffusion cells integrated in one instrument with lower space occupancy rate and higher test efficiency
3 distinct or equivalent specimens can be tested individually with independent test results at one operation
The system can be easily connected to a maximum of 10 instruments to accomplish up to 30 tests at the same time
Based on the user-friendly Windows operating interface for easy operation
Saves test data in different formats for convenient data transfer
Intelligent historical data searching, comparing, analyzing and printing functions
