C303H Water Vapor Transmission Rate Test System is based on the testing principle of infrared water vapor sensor, it is designed and manufactured according to ASTM F1249, ISO 15106-2 and other standards to provide high precision and high efficiency water vapor transmission test for high and medium gas barrier materials. It is suitable for testing the water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemical, photovoltaic, electronic and other fields.
Infrared Moisture Sensor
High Efficient Three-chamber
Safe and Reliable
The pre-treated sample is clamped between the test chambers, the nitrogen with stable relative humidity flows on one side of the film, and the dry nitrogen flows on the other side of the film; due to the existence of humidity difference, water vapor will diffuse from the high humidity side through the film to the low humidity side; on the low humidity side, the water vapor is carried to the infrared water sensor by the flowing dry nitrogen, and different water vapor is generated. The concentration produces different light signals, and the concentration value is obtained through analysis and calculation, and then the water vapor transmission rate of the sample is calculated.
ASTM F1249, ISO 15106-2, GB/T 26253, JIS K7129, YBB00092003-2015
