Product Introduction
WPT-304 Water Vapor Permeability Tester is manufactured based on the gravimetric method and is applicable to test the water vapor transmission rate of plastic films, composite films, sheets, and other materials used in packaging, medical and constructive industry.
Product Features
- Standard periodic weighing method and auto-zeroing function guarantee the accuracy and uniformity of the testing data.
- Touch interface is more convenient to operate.
- 4 specimens can be processed independently with individual result in one test automatically.
- Electric cylinder lifting structure and automatic weighing calibration mode ensure the accuracy of data.
- Innovative circulating dehumidification system can effectively prevent the formation of humidity gradient and ensure accuracy.
- High-precise and automatic control system of temperature can be used under different conditions.
- Dual test modes: water method and desiccant method.
- Adjustable air velocity enables the appropriate humidity for testing.
- The data can be stored and outputted in multi-format (including reports in excel and cloud sharing).
- GMP management of user's three-level authority complies with international standards.
- The instrument processes statistical analysis of single and group data.
- Equipped with ISP control online and upgrade function.
- Specialized communicating software can display in real-time, analyze and store data.
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.
Test Standards
This test instrument conforms to many national and international standards:
ISO 2528, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, GB/T 1037, GB/T 16928, YBB 00092003
