Note:
1. The gas supply port of instrument is Φ6 mm PU tubing;
2. Customers will need to provide gas supply and distilled water;
3. The given temperature and humidity control ranges are independently valid.
Principle
At 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 at different time, water vapor transmission rate and other parameters can be obtained.
Standards
This water vapor transmission rate testing system conforms to the following standards:
ASTM E96, ASTM D1653, ISO 2528, GB 1037, GB/T 16928, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003
i-Hydro 7320 Water Vapor Transmission Rate Testing System is designed to test water vapor transmission rate of:
| Basic Applications | Films
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum composite films, and many others |
Sheeting
Including engineering plastics, rubber, and building materials, e.g. PP, PVC, and PVDC |
Paper and Paper Board
Including paper and paper board, e.g. aluminumed paper for cigarette packages and Tetra Pak materials |
Textiles and Nonwovens
Including textiles and non-woven materials, e.g. waterproof breathable fabric, non-woven fabric for diapers and hygienic products |
| Extended Applications (Additional Accessories Required) | Inverted Cup Method
Mount film 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 |
Artificial Skin
This instrument can be used to test water vapor permeability of artificial skin |
Medical Products and Accessories
Including plasters, aseptic wound protection films, face masks, and scar sticks |
Solar Back-Sheets
Including solar back-sheets |
LCD Monitor Films
Including LCD monitor films |
Paint Films
Test water vapor permeability of various sorts of paint films |
Cosmetics
Test water vapor permeability of cosmetics |
Biodegradable Films
Test water vapor permeability of various sorts of biodegradable films, e.g. starch-based packaging films |
Functionality
Based on Water Method (ASTM E96) and strictly conforms to testing standards Individually and periodically weighing mechanism for 6 test dishes and automatic reset before weighing Wide range and automatic temperature and humidity control system to support various non-standard test conditions Standard air velocity enables uniform humidity control and improves the testing accuracy Convenient fast-access calibration port for temperature and humidity Reference film or standard weight for fast and accurate calibration Design
Weighing of test dishes is controlled by gas cylinder which ensures the accuracy and stability of test data. Individual test in 6 test dishes and test results displayed independently. Embedded computer control system provides safer and more reliable data management as well as test operation. The system can be easily connected to a maximum of 9 satellite bases to accomplish up to 60 tests at the same time. The water vapor transmission rate testing system can be easily operated with a mouse, a keyboard, and a monitor, without requiring a PC. The instrument is equipped with four USB ports and dual Internet ports for convenient input, output, and data transfer. Sophisticated energy consumption and test environment monitoring and analysis functions for better test accuracy and reliability. (Relevant sensors are needed. For more information, please refer to the configuration in Technical Specifications.) Universal power input for easy access. Software
Interface: Windows-based operating interface Statistics: easy calculation for historical results, instrument usage, energy consumption, and large statistical information Data Comparison: by presetting target value and range, the system automatically generates data comparison after each test and intelligently judges whether the specimen passes or fails the test Test Report: can provide detailed test reports in various customized patterns Energy Consumption and Test Status Monitoring (Additional Sensors Required): the system monitors and displays real-time voltage, current, energy consumption, vibration and inclination angle of instrument as well as ambient temperature and relative humidity during the test, which serves to evaluate test data reliability User Management: multi-level account management for better data management and protection Operation Log: system automatically records all the operations by the user, which is easy to review
