gas transmisson rate tester


Functions and applications


This N500G Gas Permeability Analyzer is for testing the gas  transmission rate (GTR) of following packaging materials,

① Films, such as plastic film, composite film, coextrusion film, aluminum-plated film, aluminum foil, etc;

② Sheets,such as various sheets and plates;

③ Containers,such as bottle, bag, bowl, and tube,etc;

④ extensive application,such assolar panel, LCD display film, medical patch, etc.


Working principle


Differential-pressure method. Fix the test sample between the upper chamber and lower chamber, vacuumize the whole gas circuit by vacuum pump, and add some experimental gas in upper chamber to generate constant differential pressure. The gas molecules penetrate through the sample from higher pressure room into lower pressure room, then the system monitor the pressure change in lower pressure room and calculate the gas transmission rate.


Instrument features


Design as principle of differential-pressure method GB/T1038, and compatible with YBB00082003、ASTMD1434 and so on;;

Built-in computer, can work without external computer.

Automaticoperationprocess; computer software can display testing data in real-time;

Authority management and data trace for software configuration to ensure data safety;

High precision, can test high barrier samples.
