PERME W3/330 Water Vapor Transmission Rate Test System

Product catalog summary

Overview
This document describes the Professional, High Efficiency, and Intelligent WVTR Test System designed for measuring the water vapor transmission rate (WVTR) of film and package specimens. It features three test modes suitable for materials with varying water vapor permeability and includes a high precision electrochemical sensor.

Specifications
The system offers a wide test range from 0.001 to 1000 g/m²•24h, with precise temperature and humidity control. It supports standard, proportional, and continuous testing modes to minimize human error. Calibration is facilitated by a fast-access port and reference film.

High Efficiency
The W3/330 system uses an electrolytic sensor method with a patented design of three diffusion cells, enhancing test efficiency by three times. It can connect with up to 9 satellite bases for simultaneous testing of up to 30 specimens.

Intelligent Features
The system includes user-friendly software for easy operation and intelligent data management. It supports the Lystem™ Lab Data Sharing System for uniform management of test results and reports.

Test Principle
The specimen is placed in a diffusion cell divided into dry and controlled-humidity chambers. Dry nitrogen carries water vapor permeating through the specimen to the sensor, where electrical signals are generated and analyzed to determine the WVTR.

Standards and Applications
The instrument complies with ISO 15106-3, GB/T 21529, DIN 53122-2, and YBB 00092003 standards. It is applicable to films, sheeting, paper materials, packages, and extended applications like package caps, LCD monitor films, solar back-sheets, and more.

Technical Specifications
The system supports a test range of 0.001 to 40 g/(m²·24h) for films and 0.0001 to 0.2 g/(pkg·24h) for packages. It accommodates specimens up to 3 mm thick and offers a temperature range of 15°C to 55°C with ±0.1°C accuracy.

Configurations
Standard configurations include the mainframe, software, and various accessories. Optional parts are available for package testing and temperature control.

Notes
The instrument requires a 1/8 inch copper tubing for gas supply, and users must provide gas and distilled water. Specifications are subject to change, and updates can be found on the Labthink website.

PERME W3/330 Water Vapor Transmission Rate Test System-2

permeating through the specimen from the controlled-humidity chamber is carried by dry nitrogen to the electrolytic sensor where proportion electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For package samples, dry nitrogen flows inside the package, and moisturized nitrogen flows outside. This test instrument conforms to the following standards: ISO 15106-3, GB/T 21529, DIN 53122-2, YBB 00092003 This instrument is applicable to the determination of water vapor transmission rate of: Basic Applications Paper,...
