Water Vapor Permeation Analyzer

TSY-T3 Water vapor permeation analyzer is applicable in water vapor permeability test of barrier



materials such as plastic film and laminated film. Users can control and adjust the technical index of



packaging materials by testing the water vapor transmission rate.

1. Characteristics

Cup method, high in efficiency.

12 test chambers test at same time or test in random groups.

Satisfies different test conditions, controlled automatically.

Transmission and weigh up are in same ambient, little errors caused by human operation.

Highly accurate sensor, data reliable.

Flexible heating equipment, even and gentleness.

P.I.D. system controls temperature accurately. Little temperature fluctuation.

Professional software, test data displayed dynamically.

Database mode storage, easy to analyze.

Functions of storage, researching, printing, plotting, and communication.

Computer controls automatically, easy to operate, friendly human-equipment interaction.

2. Principle

Saturated water vapor transmits through specimen in a unit time under specified conditions of temperature



and humidity. Determine the transmitted mass by test the decreasing weight of distilled water with time going.

3. Performance characteristics

? Before test, just input parameters of pre-heating time, test temperature, and so on. Tester will finish the test

automatically and print out test results.

WVTR under different conditions got, one group or multi-groups test conditions set according to actual

requirement of packaging materials.
