PERME®W3/230 Water Vapor Transmission Rate Test System Professional, High-efficiency and Intelligent WVTR System W3/230 Water Vapor Transmission Rate Test System is designed for the determination of water vapor transmission rate test of film and package specimens. It has three test modes and is applicable to various materials with high, medium and low water vapor permeability. It is also embedded with high precision infrared sensor, which provides a wide test range of 0.001～1000g/m2·24h and durable service life. Wide range and high-precision of automatic temperature and humidity control to support various combinations of non-standard test conditions Proportional, cycling and manual testing modes facilitate to test different materials with distinct water vapor permeability Convenient fast-access calibration port for temperature and humidity Reference Standard film or standard weight for fast and accurate ca

High Efficiency W3/230 system is based on the infrared sensor method and utilizes Labthink’s latest exclusive patent design of three diffusion cells integrated in one instrument for individual or multiple tests, which improves test efficiency by 3 times. It can be easily connected with 9 satellite bases to accomplish up to 30 tests at the same time. Three diffusion cells integrated in one instrument with lower space occupancy rate and higher test efficiency Three distinct or equivalent specimens can be tested individually with independent test results at one operation The system can be...

Test Principle Infrared method is used by W3/230 Water Vapor Transmission Rate Test System: 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 infrared sensor where proportion electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For package...
