Test principle
W405L water vapor transmission rate tester adopts the principle of infrared method. Fix the pre-treated sample in the middle of the test chamber, divide the test chamber into a high-humidity side and a low-humidity side, the humidified nitrogen flows on one side of the film, and the dry nitrogen (carrier gas) flows at a fixed flow rate on the other side, in the presence of a humidity gradient, water vapor will permeate from the high-humidity side to the low-humidity side, and the water vapor that passes through the sample is carried to the infrared sensor by the flowing dry nitrogen, and the water vapor transmission rate (and other parameters) of the sample is obtained by the electrical signal output by the sensor.
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.
Curves display of transmission, water vapor concentration, temperature and humidity in real time. 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.
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.
Provide electronic signature function, online report submission and review functions.
High efficiency
Three independent test chambers: With three sensors and each chamber test independently, three same/different samples can be tested at the same time and output three test reports, which improve test efficiency.
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.
Authority management and data tracking
The software is designed according to the requirements of the new GMP Appendix computerized system.
Need a user name and password to log in to the workstation, and ensure the safety and effectiveness of account and experiment data.
Users can be classified into different levels of system administrator, instrument administrator, auditor and operator.
The system administrator can adjust the permissions of various levels, for example, increase and decrease system control items of any level.
Have audit and trace functions (test tracking, log tracking), every data change is recorded, ensure the security and integrity of test data.
Reliable and easy-maintenance instrument
Our infrared sensor, with high precise and good performance, can work for a long time.
Sensor over-range automatic protection, prevent damaging important sensors while instrument failure.
Functional modular design, easy to maintain.
