W3/130 Water Vapor Transmission Rate Tester
W3/130 Water Vapor Transmission Rate Tester
The document provides detailed information about the W3/130 Water Vapor Transmission Rate (WVTR) Tester by Labthink Instruments Co., Ltd. This high-end, professional, and intelligent instrument is designed for testing the water vapor transmission rate of various film specimens using a humidity sensor method.
Specifications
The WVTR Tester features three individual test dishes allowing simultaneous testing of identical or distinct specimens with independent results. It includes a high-precision humidity sensor and supports a wide range of automatic temperature control. The instrument is equipped with a convenient calibration port and reference film for accurate calibration.
High-end Features
The W3/130 system integrates three diffusion cells in one instrument, enhancing test efficiency by three times. It uses an embedded computer control system for reliable data management and operation. The instrument can be operated via an LCD monitor, keyboard, and mouse, and includes multiple USB and Internet ports for data transfer.
Intelligent Features
The instrument's software offers a user-friendly interface with intelligent data management functions. It supports the Lystem™ Lab Data Sharing System for uniform management of test results. Features include status monitoring, sensor calibration reminders, multi-level account control, and intelligent test process guidance.
Test Principle
The test involves mounting a pre-conditioned specimen between dry and wet chambers. The humidity sensor in the dry chamber measures humidity changes to calculate the water vapor transmission rate and coefficient.
Standards and Applications
The instrument conforms to standards such as ISO 15106-1, ASTM E398, TAPPI T523, and JIS K7129. It is applicable for testing films, sheeting, paper, solar back-sheets, LCD monitor films, textiles, and aseptic wound protecting films.
Technical Specifications
The test range is 0.05 to 1000 g/m²·24h with an accuracy of 0.01 g/m²·24h. The specimen size is 108 mm x 108 mm, and the instrument supports a temperature range of 15°C to 55°C. It requires a dry air gas supply and has a net weight of 55 kg.
Configurations
Standard configurations include the mainframe, software, LCD monitor, keyboard, mouse, and other accessories. Optional parts include a reference film, sample cutter, and printer.
Note
Technical specifications are subject to change, and customers need to prepare for gas supply and distilled water. For the latest updates, visit Labthink's website.

Test 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. This test instrument conforms to the following standards: ISO 15106-1, ASTM E398, TAPPI T523, JIS K7129 Applications This instrument is applicable to the determination of water vapor transmission...
