AI Overview
This video demonstrates how a water vapor permeability analyzer works:
Key Features and Types
- Methodology: Analyzers typically use ASTM E96 (Gravimetric/Cup Method) for measuring weight change, ASTM F1249 for Infrared sensors, or ASTM D3985 for high-barrier materials.
- Precision: High-precision instruments (e.g., AUTO W806) can achieve a test resolution of up to and feature 3D constant temperature and humidity control.
- Efficiency: Many modern, automated analyzers (e.g., GBPI W301) offer multiple test chambers (e.g., three or six) for simultaneous testing of different samples.
- Application Range: Suitable for films, aluminum foil, sheets, paper, textiles, and finished packages (bags, bottles).
Commonly Used Analyzers
- GBPI W303/W812 (Gravimetric): Known for precision in measuring WVTR using weight gain/loss.
- GBPI W203 2.0 (Electrolytic): Designed for high-barrier films, such as those used in solar cells and electronics.
- WVTR Transmission Rate Analyzer (Infrared): Ideal for plastic and coated films, offering rapid results.
- ProUmid Permeability Kit: A specialized kit allowing for the simulation of specific climatic conditions (EN ISO 7783-1).
Operation and Application
- Testing Procedure: Involves placing a sample between a dry chamber and a humid chamber, then measuring the change in moisture over time.
- Applications: Essential for ensuring the shelf life of food, pharmaceutical, and electronic products by testing for moisture barrier efficiency.
- Key Industries: Quality inspection, pharmaceuticals, food packaging, and electronics.
