W3/230 Water Vapor Transmission Rate Test System


Professional, High Efficiency and Intelligent WVTR Test System



W3/230 Water Vapor Transmission Rate Test System is designed for the determination of water vapor transmission rate 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 0.1?1000g/m2·24h and durable service life.



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.




The instrument is equipped with the latest operating software, with user-friendly operating interface and intelligent data management functions. It also supports LystemTM Lab Data Sharing System, which ensures uniform management of test results and test reports.
