DH-W201 Infrared Sensor Water Vapor Transmission Rate Tester, WVTR Permeability Tester for High Barrier Films Paper Sheeting
Introduction:
DH-W201 Water Vapor Transmission Rate Tester is manufactured based on the infrared sensor method and is applicable to test the water vapor transmission rate of high barrier materials.
Features:
The touch interface is more convenient to operate.
High precise infrared moisture sensor.
One sample for each test.
The stability of the temperature and humidity is to ensure the consistency of test conditions of chambers.
High-precise and automatic control system of temperature can be used under different conditions.
The data can be stored and outputted in multi-format (including reports in excel and cloud sharing).
GMP management of the user's three-level authority complies with international standards.
The instrument processes a statistical analysis of single and group data.
Equipped with ISP control online and upgrade function.
Specialized communicating software can display in real-time, analyze and store data
Principle:
The test specimen is mounted in the diffusion cell, which is subsequently divided into a dry chamber and a controlled-humidity chamber. The dry side of the specimen is swept by a flow of dry nitrogen, and the water vapor permeating through the specimen from the controlled-humidity chamber is carried by dry nitrogen to the infra-red sensor where proportion electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For package samples, dry nitrogen flows inside the package, and moisturized nitrogen flows outside.
