Product catalog summary
Overview
The PERME®W3/230 Water Vapor Transmission Rate Test System is a professional, high-efficiency, and intelligent system designed to measure 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 infrared sensor.
Specifications
  • Test Range: 0.001~1000 g/m²·24h
  • Specimen Size: 108 mm × 108 mm
  • Temperature Range: 15℃~55℃ with ±0.1℃ accuracy
  • Humidity Range: 0%RH, 35%RH~90%RH, 100%RH with ±1%RH accuracy
  • Carrier Gas: 99.999% high-purified nitrogen
  • Instrument Size: 690 mm (L) × 350 mm (W) × 360 mm (H)
  • Weight: 70 kg
Features
  • Professional: Offers wide range and high-precision temperature and humidity control, with proportional, cycling, and manual testing modes.
  • High Efficiency: Utilizes three diffusion cells for increased test efficiency, capable of connecting with up to 9 satellite bases for 30 simultaneous tests.
  • Intelligent: Equipped with user-friendly software for data management and supports Lystem™ Lab Data Sharing System.
Test Principle
The system uses the infrared method where the specimen is placed in a diffusion cell divided into dry and controlled-humidity chambers. Dry nitrogen carries the water vapor permeating through the specimen to an infrared sensor, generating electrical signals to calculate the WVTR.
Applications
  • Basic Applications: Suitable for films, sheets, paper, and packages including plastic, rubber, and metal.
  • Extended Applications: Includes testing for package caps, LCD monitor films, solar back-sheets, pharmaceutical packaging, and more.
Standards Compliance
The instrument conforms to ISO 15106-2, ASTM F1249, TAPPI T557, and JIS K7129 standards.
Technical Specifications
  • Film Test Range: 0.001~100 g/m²·24h (Standard), 0.02~1000 g/m²·24h (Optional)
  • Package Test Range: 0.0001~0.5 g/pkg·d
  • Specimen Thickness: ≤ 3 mm
  • Test Area: 50 cm²
Configurations
  • Standard Configuration: Includes mainframe, software, pressure regulator, and other essential components.
  • Optional Parts: Satellite base, packaging testing accessories, temperature control system, and more.
Note: Customers need to prepare gas supply and distilled water.

Water Vapor Permeation and Barrier Test System-3

Test Principle Infrared method is used by W3/230 Water Vapor Transmission Rate Test System: The test specimen is mounted in the diffusion cell, which is subsequently divided into a dry chamber and a controlled-humidity chamber. The dry side of the specimen is swept by a flow of dry nitrogen, and the water vapor permeating through the specimen from the controlled-humidity chamber is carried by dry nitrogen to the infrared 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,...
