GBPI New Launch W401 2.0 Water Vapor Permeation Analyzer September 8,2021.

water vapor transmission rate of film

1.Product Introduction

Based on the testing principle of the infrared sensor, W401 is designed and manufactured with reference to the standard of GB/T 26253. It is used to test the water vapor transmission rate of film or sheet materials.

Applied to:

1)Plastic film, composite film, aluminum foil, aluminized film,etc;

2)Sheet, panel, rubber, ceramics,etc;

3)Packaging containers, such as: bottle, pouch, bowl, 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.


1)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 Mater(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.

2)Simple operation

Professional software with simple interface, easy to use and flexible to set test process.

Fully-auto operation, one-button test, judge and stop automatically.

Real time curves display of temperature, humidity, transmission, flow and Voltage. The curves with conceal function, support query function for background data.

Mainframe configure with color touch screen, can observe temperature, humidity and transmission without external computer in real time.

The sample is compressed by pneumatic clamp, which is quick and convenient to operate.

Professional test report; files can be exported in PDF.

3)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.

Provide electronic signature function, online report submission and review functions.

4)High efficiency

Single test chamber, fast data test.

Measurement precise up to 0.001 g/m2·24h, can test high barrier materials, such as aluminum foil.

5)Authority management and data tracking

The software is designed according to the requirements of the computerized system of the new GMP appendix.

Require user name and password to log in to the workstation. Ensure that the account and experimental data are safe and effective.

Users are divided into various levels such as operator and administrator, observer, etc.

Administrators can adjust permissions at various levels; for example, increase and decrease system control items at a certain level.

With audit trail function (system audit trail, project operation audit trail), every data change is recorded; the safety and integrity of test data is guaranteed.

6)Reliable and easy-maintenance instrument

Our infrared sensor, with high precise and good performance, can work for a long time.

Sensor over-range protection, prevent damaging important sensors.

Functional modular design, easy to maintain.
