GBPI Water Vapor Permeation Tester Widely used in quality inspection organizations, drug control institutions, research institutes, packaging, thin film, food companies, pharmaceutical enterprises, personal care industry, electronics industry and so on.
Test Principle
Under a certain test temperature, the constant difference of humidity is generated between two sides of the test specimen. The water vapor permeates through the specimen and is into the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.

Features
Accurate and reliable data
◆ Measurement precise up to 0.001 g/(m2·24h).
◆ Curves display of transmission, water vapor concentration, temperature and humidity in real time. The curves with conceal function, support query function for background data.
◆ Advanced electromagnetic technology, program control, auto heating and cooling simplify testing.
Intelligent control
◆ Fully-auto operation, one-button test, judge and stop automatically.
◆ Real-time display of experiment status, programmed auto-control.
◆ Password lock management for debugging parameters.
◆ Sensor over-range auto protection, prevent damaging important sensors.
Advanced technology
◆ Three independent test chambers with separate sensors; each chamber test independently, three same/different samples can be tested at the same time and output separate test report.
◆ High-efficiency water vapor generator.
◆ Advanced high-precision sensor, continuous weighing and collecting data. Test data is accuracy and reliable.
◆ By adding adaptive accessory, can test water vapor transmission of various containers.
◆ Can be expanded to 12 chambers.
