W3 130 Water Vapor Transmission Rate Tester

Packaging Testing Equipment

Professional, High-end and Intelligent WVTR Tester

Full Description

Professional, High-end and Intelligent WVTR Tester

Principle

Mount the pre-conditioned specimen between the dry and wet chambers. The humidity sensor located in the dry chamber analyzes humidity changes and calculates the time for humidity to increase from the lower preset value to the higher one. The water vapor transmission rate and water vapor transmission coefficient are consequently obtained by periodically system measurement and analysis.
