Product Description

Product Description

Scope of application:
The water vapor transmission rate tester is based on the infrared testing principle, providing a wide range and high efficiency water vapor transmission rate test for medium and high barrier materials. It is suitable for the determination of water vapor transmission rate of various high barrier materials such as plastic film, composite film, sheet materials, medical and building materials.
Film: Suitable for water vapor transmission rate test of various plastic films, plastic composite films, paper-plastic composite films, geomembranes, co-extruded films, aluminized films, aluminum foils, aluminum foil composite films, waterproof breathable films and other film materials.
Sheet: Suitable for water vapor transmission rate test of various engineering plastics, rubber, building materials (waterproof materials for construction), thermal insulation materials and other sheet materials, such as PP sheets, PVC sheets, PVDC sheets, nylon sheets, etc.
Paper and cardboard: Suitable for water vapor transmission rate test of paper and cardboard.

Product features:
1. High-precision infrared moisture sensor improves the accuracy and stability of the test.
2. High-definition LCD touch screen, more intuitive content, easier operation.
3. The three test chambers are completely independent and can test the same or different samples at the same time.
4. Wide range, high precision, automatic temperature and humidity control to meet the test under various test conditions.
5. Unique test structure, 3 chambers are tested at the same temperature and humidity to ensure the consistency of test conditions in different test chambers.
6 Test results support multi-format storage and data output, including experimental report Excel, cloud sharing.
7. The product complies with GMP user multi-level permissions.
8. Single and group statistical analysis of test results can be performed.
9. With ISP online control and upgrade functions, the test function can be remotely changed as required.
10. Specialized computer communication software can be used for real-time display of the test and data analysis and processing, and data storage.

Test principle
The instrument adopts the infrared sensor test principle. The sample to be tested is clamped between a dry and wet chamber at a constant temperature. There is a certain humidity difference on both sides of the sample. Due to the existence of the humidity gradient, water vapor will diffuse from the high humidity chamber to the low humidity chamber. In the low humidity chamber, water vapor is carried to the infrared sensor by the carrier gas. When entering the sensor, an electrical signal of the same proportion will be generated. By analyzing and calculating the sensor electrical signal, the water vapor permeability and moisture permeability coefficient of the sample can be obtained.

Test standards:
The instrument complies with many national and international standards: ISO 15106-2 , ASTM F1249, GB/T 26253-2010 , TAPPI T557, JIS K7129, YBB00092003-2015
