2. Customers will need to provide gas supply and distilled water (HPLC level);
3. The given temperature and humidity control ranges are independently valid.
Principle
Clamp the specimen in between the dry and humid constant-temperature chambers, the sensor in the testing cell detects the humidity change and traces the time spent from the preset upper limit data to the preset lower limit data. With constant and repeated measurement as well as systematic analysis, water vapor transmission rate and water vapor permeability coefficient can be obtained.

Functionality
Based on dynamic relative humidity method (ASTM E398) and strictly conforms to testing standards Three independent test cells for testing three pieces of identical or distinct samples in each test Automatic and bidirectional temperature control, and constant humidity to support various non-standard test conditions Equipped with fast-access calibration port for convenient operation Reference film for fast and accurate calibration Design
Patented design of three integrated test cells improves the test efficiency and reduces the space occupancy of the instrument. Embedded computer control system provides safer and more reliable data management as well as test operation. The water vapor transmission rate tester can be easily operated with a mouse, a keyboard, and a monitor, without requiring a PC. The WVTR 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.) 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 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
