Product Description
Product function:
It is applied to various gas permeation rate detection of O2, CO2, N2 and air, etc, in plastic film, composite membrane, High-barrier materials, sheet, metal foil, rubber, etc.
Operating principle:
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.
Application characteristic
High speed vacuum ability, reduce the vacuum time,accelerate the degassing, reduce the test error.
Short test time, high efficiency;
Could extend to test bottle, bag;
Test gas can be humidified;
Can measure any gas, including toxic gases, no gas leaking ,less gas consumption, a bottle can be used continuously for three months (not humidified);
Automatically adjust the test pressure, fit for various pressure requirements, which could be low to 1kpa.
Save functions when power failure;
A whole-process monitor, automatic recording, sampling rate could be adjusted, automatically repeat the test.
The whole process could reappear in whole process, Strong graph curve function, convenient for comparison test and analysis;
Automatic testing: Set the test parameters, test automatically proceeds after starting, automatically judge 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 iseasy to grasp the history dynamic of the products.
Product feature
Pure semiconductor temperature controlled, 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
Meeting Standards
Compatible with the standard of various tests ISO, etc: ASTM D1434,ISO 2556,ISO 15105-1,JIS K7126-A,YBB 00082003
