W3/030 Water Vapor Transmission Rate Tester is based on the cup method, and is professionally applicable to the water vapor transmission rate test of plastic films, composite films, sheets and other materials used in medical and construction industry. By testing the water vapor transmission rate, the technical index of the materials could be controlled to meet the requirements for production.
Standard periodically weighing method and auto zero before each weighing guarantee the accuracy and uniformity of the testing data
Three specimens could be tested simultaneously and the test dishes are lifted and lowered by the gas cylinder which ensures the reliability of the test
Standard air velocity to prevent the humidity difference spread which ensures the accuracy of the test
Wide range and high-precision of automatic temperature and humidity control to support various combinations of non-standard test conditions
Equipped with fast access calibration ports for temperature and humidity which is convenient to the user
Wide range power input is available
Universal RS232 communication port is convenient to the data export and transmission
Reference film or standard weight for fast and accurate calibration
Supports LystemTM Lab Data Sharing System for better data management
