W3/0120 Water Vapor Transmission Rate Tester

Product catalog summary
Overview: The W3/0120 Water Vapor Transmission Rate Tester by Labthink Instruments Co., Ltd. is designed for testing the water vapor transmission rate of various materials such as plastic films, composite films, and sheets, primarily used in medical and other industries. This helps in controlling the technical index of materials to meet production requirements.
Professional Technology: The tester uses a standard periodically weighing method with automatic reset for accurate data. It can test up to 12 specimens individually, maintaining a constant humidity difference with standard air velocity. It features automatic temperature and humidity control, fast access testing ports, and is computer-controlled with an automatic test process. Data export is facilitated through a universal RS232 communication port, and it supports the Lystem™ Lab Data Sharing System.
Test Principle: The test involves creating a constant humidity difference across the specimen at a set temperature. Water vapor permeates through the specimen, and by measuring weight changes over time, the water vapor transmission rate is determined.
Standards Compliance: The instrument complies with standards such as ISO 2528, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003, GB/T 16928, and GB 1037.
Applications: The tester is applicable for films, sheeting, paper and paperboard, textiles, and nonwovens. Extended applications include testing artificial skin, medical products, solar back-sheets, LCD monitor films, paint films, cosmetics, and biodegradable films.
Technical Specifications: The tester has a test range of 0.1 to 10,000 g/m²·24h, with a test accuracy of 0.01 g/m²·24h and a resolution of 0.0001 g. It supports a temperature range of 15°C to 65°C with ±0.1°C accuracy, and a humidity range of 40%RH to 95%RH with ±1%RH accuracy. The air velocity is customizable between 0.5 to 2.5 m/s.
Configurations: Standard configurations include the mainframe, professional software, test dishes, desiccant tube, automatic moisture filter, standard weight, round sample cutter, and communication cable. Optional parts include a reference film, air compressor, and desiccant. Customers need to prepare gas supply and distilled water.
Note: Labthink is committed to continuous innovation and improvement, and technical specifications may change without notice. For the latest updates, visit their website.

W3/0120 Water Vapor Transmission Rate Tester-1

PERME® W3/0120 Water Vapor Transmission Rate Tester W3/0120 Water Vapor Transmission Rate Tester is based on the cup method, and is professionally applicable to the water vapor transmission rate test of plastic films, composite films, sheets and other materials used in medical and other industry. By testing the water vapor transmission rate, the technical index of the materials could be controlled to meet the requirements for production. Professional Technology Standard periodically weighing method and automatic reset before weighing ensures accurate weighing data 12 distinct or equivalent specimens can be tested individually with independent test results at one operation Standard air velocity enables constant humidity difference between two sides of test dishes Wide range and high-precision of automatic temperature and humidity control to support various combinations of non-standard test conditions Equipped with fast access testing ports for temperature and humidity which is convenient to the user System is controlled by computer with automatic test process Universal RS232 communication port is convenient to the data export and transmission Reference film or standard weight for fast and accurate calibration Support Lystem™ Lab Data Sharing System for uniform and systematic 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, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003, GB/T 16928, GB 1037 Applications This instrument is applicable to the determination of water vapor transmission rate of: Including plastic films, plastic composite films, paper-plastic composite Films Basic Applications films, geomembranes, coextruded films, aluminized films, aluminum foils, aluminum composite films, breathable water-proof films and many other film materials Sheeting Paper and Paper Board Including engineering plastics, rubber, building materials and many others, e.g. PP, PVC, and PVDC Including paper and paper board, e.g. aluminum foil paper for cigarette packages and Tetra Pak materials Labthink Instruments Co., Ltd.144 Wuyingshan Road, Jinan, P.R.China (250031) Phone: +86 -531-85068566 FAX: +86-531-85812140 w w w.labthinkinter n atio n al.co m.cn
