Fabric Water Vapor Permeability Tester

W3/130 Fabric Water Permeability Tester is based on the humidity sensor method, are designed to measure the WVTR of flexible films, sheets, foils and etc. It has 3 test cups, which can test independently.

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.

Standards:

• ISO 15106-1, ASTM E398, TAPPI T523, JIS K7129
  

Features:

• Based on the humidity sensor method.
• 3 identical or distinct specimens can be tested simultaneously with independent test results.
• Equipped with high-precision humidity sensor to ensure accurate test result.
• Wide range and high-precision of automatic temperature control to support various combinations of non-standard test conditions.
• Convenient fast-access calibration port for temperature.
• Reference film for fast and accurate calibration.
• 3 diffusion cells integrated in one instrument with lower space occupancy rate and higher test efficiency.
• Equipped with Labthink's latest operating software, with user-friendly operating interface and intelligent data management functions.
• Supports LystemTM Lab Data Sharing System, which ensures uniform management of test results and test reports.
