Gas Permeability Tester

Product catalog summary

Overview
The document provides detailed information about the PERME®W3/060 Water Vapor Transmission Rate (WVTR) Test System, which is designed to measure the water vapor transmission rate of various materials including films, sheeting, paper, textiles, and more.

Applications
The system is applicable to a wide range of materials such as plastic films, geomembranes, engineering plastics, paper boards, textiles, medical products, solar back-sheets, LCD monitor films, paint films, cosmetics, and biodegradable films. It is particularly useful for testing the water vapor permeability of artificial skin and other medical accessories.

Test Method
The system uses the inverted cup method, where a film or sheeting is mounted in a test dish with distilled water on one side and a controlled humidity on the other. The water vapor transmission rate is determined by measuring weight changes over time.

Humidity Range: 10%RH to 98%RH
Air Velocity: 0.5 to 2.5 m/s
Specimen Thickness: ≤ 3mm
Instrument Size: 660mm(L)×480mm(W)×525mm(H)
Power: AC (85 to 264)V (47 to 63)Hz
Net Weight: 70kg

System Features
The system is equipped with professional software for easy operation and data management. It supports the LystemTM Lab Data Sharing System for systematic management of test results. The system allows for high precision and efficiency, with the capability to test up to 60 specimens simultaneously when connected with satellite bases.

Standards Compliance
The instrument conforms to various international standards including ISO 2528, GB 1037, ASTM E96, and others, ensuring reliable and standardized test results.

Configuration
The standard configuration includes the main body, professional software, test dish, desiccant tube, automatic moisture filter, calibration weight, communication cable, round sample cutter, and valve set. Optional parts include a satellite base, reference film, air compressor, and desiccant.

Conclusion
The PERME®W3/060 WVTR Test System is a professional, high-efficiency, and intelligent solution for measuring water vapor transmission rates across a variety of materials, providing accurate and reliable data for research and quality control purposes.

Water Vapor Transmission Rate Test System Test Range Temperature Range Humidity Range Test Area Specimen Size Test Chamber Size Specimen Thickness Port Size Power Instrument Size Applications This instrument is applicable to the determination of water vapor transmission rate of: Films Basic Applications Including plastic films, plastic composite films, paper-plastic composite films, geomembranes, coextruded films, aluminized lms, aluminum foil, aluminum composite lms, breathable waterproof lms, and many others Including engineering plastics, rubber, and building materials, e.g. PP, PVC, and PVDC Paper and Paper Board Including paper and paper board, e.g. aluminum foil paper for cigarette packages and Tetra Pak materials Including textiles and non-textiles materials, e.g. waterproof breathable fabric, non-woven fabric for diapers and hygienic products Mount lm or sheeting in test dish, cover upper surface of specimen with distilled water, and make the lower side in certain humidity. Generate a constant humidity difference between two sides; water vapor permeates through specimen and measure weight changes in different time to obtain the water vapor transmission rate. NOTE: inverted cup required Articial Skin Extended Applications Articial skin has to meet standard requirements for water vapor transmission rate to ensure better breath performance. This instrument can be used to test articial skin water vapor permeability Medical Products and Accessories Including plasters, aseptic wound protecting lms, face masks, and scar sticks Solar Back-Sheets Including solar back-sheets Paint Films Test water vapor permeability of various sorts of paint lms Test water vapor permeability of cosmetics Biodegradable Films Test water vapor permeability of various sorts of biodegradable lms, e.g. starch-based packaging lms Configurations Standard Conguration Optional Parts Note 1~6with independent test results Technical Specifications Including Mainbody, Professional Software, Test Dish, Desiccant Tube, Automatic Moisture Filter, Calibration Weight, Communication Cable, Round Sample Cutter, and Valve Set Including Satellite Base, Reference Film, Air compressor, and Desiccant 1.
