GBPI W402 High Efficiency Water Vapor Permeation System

Application
W402 water vapor permeability analyzer is to test the water vapor transmission rate
(WVTR) of films or sheets materials.
Applied to:
1) Plastic film, composite film, aluminum foil, aluminized film,etc;
2) Sheet, panel, rubber, ceramics,etc;
3) Packaging containers, such as: glass, bottle, cans, boxes, etc;
4) Expanding application: solar panel, LCD film, medical patch, etc.
Widely used in quality inspection organizations, drug control institutions,
research institutes, packaging, thin film, food companies, pharmaceutical
enterprises, personal care industry, electronics industry and so on.

Standard
GB/T 26253-2010，YBB 00092003-2015，BS EN ISO 15106-2-2005，ASTM F1249-2013，JIS
K7129-2008
Features
Accurate and reliable data
With The State Certificate for Gradation of the certified Reference Materials and
Licence for Manufacturing Measuring Instruments of the state Reference Materials
（GBW(E)130543/4）of Water Vapor Permeability Analyzer approved and issued by
General Administration of Quality Supervision, Inspection and Quarantine of the
P.R.C. Adopting state reference materials to calibrate and verify the instruments,
ensure the accuracy, universality and authority of the test data.

Simple operation
Professional software with simple interface, easy to use and convenient to set
test process.
Fully-auto operation, one-button test, judge and stop automatically.
Programmed auto-control, the experiment status display in real time.
Real time curves display of transmission, water vapor concentration, temperature
and humidity. The curves with conceal function, support query function for
background data.
Configure with color touch screen, can observe temperature, humidity and
transmission without external computer.
Professional test report; can be exported as PDF.

Advanced technology
Temperature control: International advanced electromagnetic technology, program
controlled, auto heating and cooling; no need of external accessories. Precision:
0.1℃.
Humidity control: Dual gas flow method(dry gas and humid gas), high precision
(1%RH) and stable flow.
Carrying cutting-edge ARM controlling system, can run independently without
computer.

High efficiency
Two independent test chambers: With two sensors and each chamber test
independently, two same/different samples can be tested at the same time and output
two test reports, which improve test efficiency.
With three different test modes of high, medium and lower barriers, can test
films with different barrier property.
Measurement precise up to 0.001 g/m2·24h, can test high barrier materials, such
as aluminum foil.
By adding adaptive accessory, can test water vapor transmission of various
containers such as bag, bottle, can and bowl.

Calibration & Certification
The instrument supports two methods of reference materials and standard gas to
calibrate and certificate; operation is simple, user only need use certified
reference materials for normal testing, and then input the test result into the
instrument interface.

Reliable and easy to maintain
Imported infrared sensors, with high precision and good performance, can work for
a long time.
Sensor over-range auto protection.
Function modularization, easy to maintain
