Product Description:
XHS-WVTR Water Vapor Transmission Rate Test System, is designed and manufactured based on infrared sensor method and conforms to the requirements of ISO 15106-2 and ASTM F1249. This instrument can be used to measure the water vapor transmission rate of barrier materials with high, and medium moisture barrier properties with a wide testing range and high testing efficiency. The instrument is featured with patented design of integrated block consisting of 3 test cells. Equipped with high precision sensors and professional computer-controlled system, the instrument can regulate and control the temperature, humidity and flow rate precisely, which guarantee the testing sensitivity and repeatability of test results. XHS-WVTR is applicable to determination of water vapor permeability of plastic films, sheeting, paper, packages and other relative packaging materials in food, pharmaceutical, medical apparatus, consumer goods, photovoltaic and electronic industries, etc.
Principle:
The test specimen is mounted in the diffusion cell, which is 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 infrared sensor where proportional electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For whole package specimens, the dry nitrogen flows inside the specimen while the outside of specimen is maintained in a high humidity environment.
Test Standards: ISO 15106-2, ASTM F1249, GB/T 26253, JIS K7129, YBB 00092003-2015
