Molecules of oxygen, diffusing through the film, are carried by nitrogen to a precision sensor that directly measures oxygen content for display without complex extrapolation
The series 8000 analysers from Systech Instruments are simple to use, modular systems for the precise analysis of the oxygen permeation performance of packaging film up to 1.27mm thick.
Two models are available; the 8000 has a very wide measurement range of 0.008 to 432,000cc/m2/day, and the 8500, suitable for less demanding applications, has a range of 50 to 99,999cc/m2/day.
In both models, the analysis is achieved without complex extrapolations providing a unique combination of speed and precision.
The control software, run on any Windows platform, combines a user-friendly interface that automatically guides the operator through the test procedure.
The heart of the series 8000 instruments is a modular test chamber into which a 100cm2 sample of the film is placed.
Pure oxygen is fed above the sample and nitrogen below.
Molecules of oxygen, diffusing through the film, are carried by the nitrogen to a precision sensor that directly measures oxygen content for display without complex extrapolation.
The model 8000 has two test chambers and up to four expansion modules can be fitted to provide up to a total of ten test chambers.
All standard and expansion test chambers use the same oxygen sensor ensuring single calibration accuracy and repeatability.
The Windows software controls all operations from calibration and test chamber purging to temperature and humidity simulation and test results analysis.
Tabbed primary screens, drop down menus and pop-up data fields combined with process automation provide a functional and simple to use operational environment.
Calibration can be by both standard gas and NIST traceable films for film-to-film comparison and data reliability. All data can be tracked, stored and output in a range of common file formats.
Conforming to European, American, and Asian test standards, the Systech series 8000 high performance oxygen permeation analysers combine simplicity with flexibility and precision.
