Note:
1. The gas supply port of instrument is Φ4 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
The test specimen is mounted within a test dish. 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 from the higher concentration side to the lower side. The permeant water vapor is then carried away by a flow stream of dry gas, and the weight loss of the test dish is intermittently measured to obtain the water vapor transmission rate.
Standards
This moisture vapor transmission rate tester (MVTR tester) conforms to the following standards:
ASTM E96, ASTM D1653, ISO 2528, TAPPI T464, DIN 53122-1, JIS Z0208, GB 1037, GB/T 16928, YBB 00092003
This MVTR tester is designed to determine water vapor transmission rate of:
| Basic Applications | Films
Including plastic films, plastic composite films, paper-plastic composite films, geomembranes, coextruded films, aluminized films, aluminum foils, aluminum composite films, breathable water-proof films and many other film materials |
Sheeting
Including engineering plastics, rubber, waterproof building materials, and thermal insulation materials, e.g. PP, PVC, PVDC, and nylon |
Paper and Paper Board
Including paper and paper board |
Textiles and Nonwovens
Including textiles and non-woven materials |
Aseptic Wound Protection Films and Face Masks
Including aseptic wound protecting films, face masks, and protection clothing materials |
| 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 |
Solar Back-sheets
Including solar back-sheets and OLED packaging materials |
LCD Monitor Films
Including LCD monitor films |
Functionality
Based on Water Method (ASTM E96) and strictly conforms to testing standards Individually and periodically weighing mechanism for 3 test dishes 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
Gas cylinder controlled mechanism to lift and lower the dishes which ensures the accuracy and stability of test results. Embedded computer control system provides safer and more reliable data management as well as test operation. The moisture vapor transmission rate (MVTR) tester can be easily operated with a mouse, a keyboard, and a monitor, without requiring a PC. The MVTR tester is equipped with four USB ports and dual Internet ports for convenient data transmission. 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.) 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
