Water Vapor Transmission analyzer - W 320

Functions and Features :

1) It has two test chambers with two sensors, and is a self standing instrument and

it gives simultaneous test reports;
2)It measures trace water vapor transmission rates in packaging barrier films;
3)Testing result is high precision;

4) With LCD screen display;
5) It adopt TCP/IP interface, so it is easy to inspect the running state,

all testing controlled by computer automatically, the result can be showed

by curve accurately and the testing report can be printed out;

6) The dual-testing mode (increasing and decreasing weight methods) is initially adopted;

7) Testing curve could spontaneously show the permeation, temperature, humidity

and the weight of water permeating cup;

8) It can finish auto-judging, auto-outage, and auto-storage of the datas;

9) Technical standard ISO2528:1995; GB/T1037-1988; GB/T16928-1997 ; YBB00092003;

ASTM F1770, ASTM D1653-03 ; ASTM E96-00e1; ASTM E-398; TAPPI T464.
