Product catalog summary

Overview
The PERME®W3/031 Water Vapor Transmission Rate Tester is a professional, high-end, and intelligent device designed for testing the water vapor transmission rate (WVTR) of film specimens using the cup method. It features automatic testing processes and adheres to international standards.

Professional Features

Utilizes a standard periodically weighing method.
Offers a wide range and high-precision automatic temperature and humidity control.
Maintains a constant humidity difference with standard air velocity.
Includes a fast-access calibration port for temperature and humidity.
Allows for quick and accurate calibration using reference films or standard weights.

High-end Features

Incorporates Labthink’s patented mechanical structure for precise data during weighing.
Features an embedded computer control system for reliable data management.
Operable via an LCD monitor, keyboard, and mouse without a PC.
Equipped with four USB ports and dual internet ports for data transfer.

Intelligent Features

Includes user-friendly software with intelligent data management.
Supports LystemTM Lab Data Sharing System for uniform test result management.
Provides intelligent sensor calibration reminders and embedded help documents.
Offers multi-level account control for data protection.
Automatically compares data after each test and supports calibration data recovery.

Test Principle
The device creates a constant humidity difference across the test specimen at a set temperature. Water vapor permeates through the specimen, and the rate is determined by measuring weight changes over time.

Standards Compliance
Conforms to ISO 2528, GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003.

Applications

Films: plastic, composite, geomembranes, aluminized, and more.
Sheeting: engineering plastics, rubber, waterproof materials.
Paper and Paper Board.
Textiles and Non-Textiles.
Extended applications include inverted cup method, solar back-sheets, LCD monitor films, aseptic wound protecting films, and face masks.

moisture Vapor Permeation Testing Instrument-3

Calibration data recovery function to reduce mistaken operation affects Lystem TM Lab Data Sharing System for better data management 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、...
