China Water Vapor Transmission Rate Tester

W202 Water Vapor Transmission Rate Tester
Functions
To test the water vapor transmission rate (WVTR) of packaging materials, 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.

Standards
ISO 15106-2, ASTM F1249, TAPPI T557, JIS K7129, GB/T26253
Features
1. Temperature control: International advanced electromagnetic technology, program controlled, without external accessories. Precision 0.1ºC.
2. Humidity control: Two-way gas flow method, with broad range, high precision and stable flow.
3. Standard gas calibration and standard film calibration.
4. Auto judgment and auto stop.
5. Leakage protection; over range protection; auto save data when power is cut off; incorrect operation warning.
6. Wholly automatic, software easy to use. Curves of transmission rate, water vapor density, humidity and temperature, auto record and continuous display. Can monitor interaction of parameters and the whole testing process.
7. Highly modularized. Setting, testing, baseline, calibration, report etc are independent. Powerful data analysis. Easy to operate.
8. Built-in computer, can work without external computer.
9. Support quick test, applicable to evaluation test.
10. Two chambers can work independently at the same time for two different samples.
11. Software upgrade, data backup and fault diagnosis through USB port.
