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,degassing more thoroughly, reduce the test error.

Short test time, high efficiency;

Could extend to test bottle, bag;

Save when power failure functions;

Little gas consumption, one bottle of gas could be used for one month continuously.

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 is easy to grasp the history dynamic of the products.

 

Product feature

Pure semiconductor temperature controlled, automatically control temperature warming and cooling. Temperature range is more wide 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, large liquid crystal display, host and PC machine double control and double operation

 

Meeting Standards

Compatible with the standard of various tests ISO, etc: ASTM D1434ISO 2556ISO 15105-1JIS K7126-AYBB 00082003
