The W330 Model Water Vapor Permeation Analyzer ensures the high precision of the testing results, with its accurate electro-magnetic balance type weighing cell and the circuit handling. It can precisely control the temperature and simulate the humidity. The dual-testing mode (gaining and losing weight methods) is initially created. Testing curve could spontaneously show the permeation, temperature, humidity and the weight of water permeating cup It also features auto-judging ,auto-outage ,and auto-storage of the data’s. The obligate TCP/IP interface makes it easy to inspect the running state. The computer controls the instrument through the USB.
