The Water Vapor Transmission Rate (WVTR) Tester is manufactured based on the infrared sensor method and is applicable to test the water vapor transmission rate of medium and high barrier materials such as plastic films, composite films, sheets, papers and other various materials.
Principle:
The test specimen is mounted in the diffusion cell, which is divided into a dry chamber and a controlled humidity chamber. A flow of dry nitrogen sweeps the dry side of the specimen, while the dry nitrogen carries the water vapor permeating through the specimen from the controlled humidity chamber to an infrared sensor. This sensor generates proportional electrical signals based on the water vapor concentration. The water vapor transmission rate is determined by analyzing and calculating these electrical signals. For package samples, dry nitrogen flows inside the package, while humidified nitrogen flows outside.
Water Vapor Transmission RFGRate Tester Features:
13-inch touchscreen tablet running on the Windows 10 operating system.
This WVTR tester is designed and manufactured according to the infrared sensor method and meets the requirements of ISO 15106-2 and ASTM F1249.
High precision sensors ensure high accuracy and repeatability of the WVTR measurement system.
Three diffusion cells are integrated into a single instrument and share the same temperature and humidity, ensuring consistent test conditions across all test cells.
Three distinct or equivalent specimens can be tested individually, providing independent results in a single operation.
Equipped with a dual-flow dry-wet humidity control system, it can achieve three-stage humidity control ranges: 0% RH, 35% to 90% RH, and 100% RH, with an accuracy of up to ±1% RH.
The high-precision temperature control system can precisely regulate temperature within the range of 10°C to 60°C, with an accuracy of up to ±0.1°C.
A reference film for fast calibration ensures accurate and universal test data (optional).
The WVTR tester is equipped with SCITEK latest operating software, featuring a user-friendly interface, intelligent data processing, strict user management, secure data storage, electronic signature, etc.
