Product catalog summary

Overview
The document provides detailed information about the W3/031 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 film specimens using the cup method.

Specifications
The WVTR Tester features a test range of 0.1 to 10,000 g/m²·24h, with an accuracy of 0.01 g/m²·24h and a resolution of 0.0001g. It supports a temperature range of 15°C to 55°C with an accuracy of ±0.1°C, and a humidity range of 10% RH to 98% RH with an accuracy of ±1% RH. The instrument can test up to three specimens independently and is equipped with a mechanical weighing system and an embedded computer control system.

Procedures
The testing process is fully automatic and conforms to international standards such as ISO 2528, ASTM E96, and others. The instrument uses a standard periodically weighing method and auto zero before each weighing to ensure accuracy. It also features fast-access calibration ports for temperature and humidity.

Applications
The WVTR Tester is applicable to a wide range of materials including plastic films, paper-plastic composite films, geomembranes, engineering plastics, textiles, and more. It also supports extended applications like solar back-sheets and aseptic wound protecting films.

Intelligent Features
The instrument includes user-friendly software with intelligent data management functions, supporting the Lystem™ Lab Data Sharing System for uniform management of test results. It offers multi-level account control, detailed data saving, and calibration data recovery functions.

Technical Specifications
The instrument dimensions are 580 mm (L) x 680 mm (W) x 470 mm (H) with a net weight of 83 kg. It requires a power supply of AC (85 ~ 264)V (47 ~ 63)Hz and a gas supply pressure of 0.6 MPa.

Configurations
Standard configurations include the mainframe, LCD monitor, keyboard, mouse, test dishes, and professional software. Optional parts include a reference film, air compressor, and printer.

Notes
Labthink emphasizes continuous innovation and improvement, and technical specifications are subject to change. Customers are advised to prepare for gas supply and distilled water.

W3/031 Water Vapor Transmission Rate Tester-2

Test Principle Under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained. This test instrument conforms to the following standards: ISO 2528, GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003 Applications This instrument is applicable to the determination of water vapor transmission rate of:...
