W301 water vapor transmission tate tester

Key Attributes.

The GBPI model W301 has one test chamber with one sensor, and is a self standing instrument. Model W301 gives simultaneous test reports. It measures trace water vapor transmission rates in packaging barrier films. Model W301 ensures the high precision of the testing results with its accurate electromagnetic balance type weighing cell and the circuit handling. It can precisely control the temperature and simulate the humidity. The dual-testing mode (increasing and decreasing weight methods) is initially adopted. 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 datas. The adopted TCP/IP interface make it easy to inspect the running state, controlled by computer through USB. It is designed and manufactured according to the standard ISO2528: 1995GB/T1037-1988 GB/T16928-1997 YBB00092003ASTM F1770ASTM D1653-03 ASTM E96-00e1, ASTM E-398, TAPPI T464.
