W301 water vapor transmission rate tester has one test chamber with
one sensor, and is a self standing instrument.
Model W301 water wapor transmission tester 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 data's. 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
