AI Overview
High-accuracy Water Vapor Transmission Rate (WVTR) testers, such as the
Labthink C390H and MOCON Aquatran 3/40, utilize advanced infrared or electrolytic sensors to measure moisture permeability in packaging materials. These systems offer ppb-level resolution, precise climate control, and compliance with ASTM F1249/ISO 15106 standards, ensuring consistent, repeatable results for high-barrier films.Key Features of High-Accuracy Models
- Detection Method: Primarily infrared sensor (ASTM F1249) for rapid response or electrolytic (ISO 15106-3) for high sensitivity.
- Sensitivity: Capable of measuring extremely low transmission rates (ppb or low g/·day).
- Environmental Control: Automated and precise regulation of temperature, humidity, and flow rate.
- Efficiency: Multi-chamber designs (e.g., 3 or 4 chambers) allowing multiple independent tests concurrently.
- Applications: Suitable for films, aluminum foil, laminates, and finished packaging containers.
Common Standards Supported
- ASTM F1249: Standard Test Method for Water Vapor Transmission Rate Through Plastic Film and Sheeting Using a Modulated Infrared Sensor.
- ISO 15106-2: Plastic film and sheeting — Determination of water vapour transmission rate — Part 2: Infrared detection method.
- ASTM E96: Standard Test Methods for Water Vapor Transmission of Materials (Gravimetric method).
