WVTR-W6 Water Vapor Transmission Rate Tester

WVTR-W6 Water Vapor Transmission Rate Tester

Product catalog summary
Overview
The WVTR-W6 Water Vapor Transmission Rate Tester by Pubtester Instruments Co., Ltd. is designed for measuring the water vapor transmission rate (WVTR) of various materials using the gravimetric method. It is suitable for materials such as plastic films, composite films, and medical materials.

Product Features
  • Advanced Technology: Dual test modes (Desiccant and Water methods), high-precision weighing system, circular test chamber design for uniform temperature and humidity distribution, and automatic temperature and humidity control.
  • High-end Configuration: User-friendly Windows interface, automatic test process recording, curve chart analysis, data traceability, and lifetime software upgrades.

Test Principle
The tester uses a gravimetric determination method where a constant humidity difference is maintained across the test specimen. The water vapor permeates through the specimen, and the weight changes are measured over time to determine the WVTR.

Applications
  • Basic Applications: Suitable for films, sheeting, textiles, non-woven fabrics, paper, and paper boards.
  • Extended Applications: Includes testing for artificial skin, cosmetics, aseptic films, LCD displays, solar back-sheets, paint films, and biodegradable films.

Technical Specifications
  • Test Range: 0.1~10,000 g/m²·24h (Water Method), 0.1~2,500 g/m²·24h (Desiccant Method).
  • Number of Specimens: 1 to 6 independent testing results.
  • Test Accuracy: 0.01 g/m²·24h with a resolution of 0.0001 g.
  • Temperature and Humidity Range: 15°C to 60°C with ±0.1°C accuracy, 10%RH to 98%RH with ±1%RH accuracy.
  • Power Supply: 220VAC 50Hz / 120VAC 60Hz.

Standards
The tester complies with various international standards including ASTM E96, ASTM D1653, GB 1037, and ISO 2528.

Configuration
The standard configuration includes the instrument, temperature control device, professional software, and other necessary components. Optional configurations include an air compressor and GMP software.

Notes
Customers need to prepare for gas supply and distilled water. The gas supply port uses Φ6 mm PU tubing.
