W 330 Water Vapor permeation analyzer - W 330

Function and Usages:

1) It has three test chambers with three separate sensors, and is a self standing instrument;

2) Measures trace water vapor transmission rates in packing barrier films;

3) Testing result is high precision;

4) 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;

5) LCD screen diaplay;

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

and the weight of water permeating cup;

7) It is auto-judging, auto-outage, and auto-storage of the datas;

8) Technical standards: ISO2528:1995, GB/T1037-1988 , GB/T16928-1997 , YBB00092003,

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

Product Features

1. Automatically control, three samples can be tested independently or with combination form,

each chamber can be set different temperatures, and tested different samples;

2. The mainframe through the USB port connect to computer, or without connecting computer,

you can use the true color touch screen to work independently;

3. The sample can be tested by single chamber, or double chambers or three chambers;

4. Controlling methods of electromagnetic technology, excellent structure and accuracy

temperature;

5. The unique design of dehumidification chamber, using the reference flow ratio method to

control humidity, excellent performance of controlling wet;

6. Simple operation, prevention function for parameter setting errors;

7. The curves of each chamber's temperature, humidity, weight, and transmission display

indepently , continous to display four groups curve, can monitor the interaction of parameters;

8. The software interface supports dynamic display of data;

9. The software interface supports the dynamic scaling curve;

10. The software displays status of each curve in time;

11. With data storage capabilities to facilitate the analysis of experimental results;

12. Optional pairs of air humidity controlling devices, more precise of controlling wet;

13. Optional weight method, to achieve double test method.
