This water vapor transmittance tester is applicable to the measurement of water vapor transmittance of plastic film, composite film, sheet materials, building materials and other high barrier materials. Based on the principle of infrared method, features high efficiency and wide test range.



High precision infrared moisture sensor improves the accuracy and stability of the test

• High definition LCD touch screen, more intuitive content and easier operation

• Four test chambers are completely independent, and four identical or different samples can be tested at the same time

• A test chamber is used as the reference chamber to determine whether the test standard membrane data is accurate

• Three test chambers are used to test samples to ensure that three parallel samples can be tested at a time

• Wide range, high-precision, automatic temperature and humidity control to meet the test under various test conditions

• Unique test structure, four chambers are tested at the same temperature and humidity to ensure the consistency of test conditions of different test chambers

• Test results support multi format storage and data output, including experimental report Excel and cloud sharing

• The product complies with the GMP user's multi-level permissions

• Single and group statistical analysis of test results can be conducted

• It has ISP online control and upgrade functions, and can change the test function remotely as required

• Special computer communication software, which can perform real-time display of test, data analysis and processing, and data storage


Test principle

The test principle of infrared sensor method is adopted. The sample to be tested is clamped between the dry and wet chambers with constant temperature. There is a certain humidity difference on both sides of the sample. Due to the existence of humidity gradient, the water vapor will diffuse from the high humidity chamber to the low humidity chamber. In the low humidity chamber, the water vapor is carried to the infrared sensor by the carrier gas. When it enters the sensor, it will generate an electrical signal of the same proportion. Through the analysis and calculation of the electrical signal of the sensor, Thus, the water vapor transmission rate and moisture permeability coefficient of the sample can be obtained.
