GBPI W401 Water Vapor Permeability Analyzer

Application
W401 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 a 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 concealing function, support query function for background data.
Configure with color touch screen, can observe temperature, humidity, and transmission without an 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 for 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 systems can run independently without a computer.

High efficiency
Three different test modes of the high, medium and lower barriers can test films with different barrier
properties.
Measurement precise up to 0.001 g/m2·24h, can test high barrier materials, such as aluminum foil.
By adding an 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, the user only needs to use certified reference materials for normal testing, and then
input the test result into the instrument interface.
Reliable and easy-maintenance instrument
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
