AUTO W46/1 - Water Vapor Permeability
by Infrared Method

The AUTO W46/1 Water Vapor Transmission Rate (WVTR) Tester is based on the infrared testing principle and is designed in accordance with GB/T 26253, ASTM F1249, and other relevant international standards.
It is used to measure the water vapor transmission rate of samples under controlled temperature and humidity conditions, providing accurate evaluation of moisture barrier properties.
This instrument is suitable for testing films, sheets, paper, packaging materials, and other related products used in industries such as:
- Food packaging
- Pharmaceutical products
- Medical devices
- Daily chemical products
- Photovoltaic and electronics industries
The system is widely used for both in-line and off-line testing of barrier properties in packaging production environments. It is an ideal solution for manufacturers requiring reliable, high-precision, and efficient moisture permeability testing for quality control and R&D applications.
