It is applied to various gas permeation rate detection of O2, CO2, N2 and air, etc. Also in plastic film, composite membrane, High-barrier materials, sheet, metal foil, rubber, etc.
Using the principle design of differential pressure method, put treated sample in the middle of upper and bottom chamber in advance. Pressure tightly and seal,pick up the suction to the whole system, after reaching the required vacuum degree, close bottom chamber, fill with certain test gas to high pressure chamber, and adjust upper chamber pressure, keep on two sides of the sample forming constant air pressure gradient difference, the gas is under the action of differential pressure gradient, permeating from high-pressure side (upper chamber) to vacuum side (bottom chamber).Accurately measure vacuum chamber (bottom chamber) intensity of pressure variation, calculate various barrier property parameters of test sample. Fully conform to the standard ASTM D1434.
High speed vacuum ability, reduce the vacuum time,accelerate the degassing, reduce the test error.
Short test time, high efficiency;
Can measure toxic gases, no gas leak;
Automatically adjust the test pressure, fit for various pressure requirements;
Save functions when power failure;
A whole-process monitor, automatic recording, can reappear in the whole test process again
Strong graph curve function, convenient for comparison test and analysis;
Automatic testing: Set the test parameters, test automatically proceeds after starting, automatically judge if the test is over and save the test result.
There is general data base system in host software, data could be exported, could store the data, inquire, print, etc. Through the analysis of historical data,it is easy to grasp the history dynamic of the products.
Pure semiconductor cold and heat bidirectional temperature control, automatically control temperature warming and cooling. Temperature range is wider and more accurate,parallel work, higher reliability.
Apply base line technology; remove the system error, test result is more accurate.
Be of accurate pressure control ability, maintaining constant pressure difference.
Adopt top grade high precision vacuum transducer, high quality component and part, precise pipeline system and pressure sensor, ensure stability and reliability of instrument running
Embedded system control, fully controlled by computer
