Product function:

It is applied to various gas permeation rate detection, such as O2CO2N2 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 GB1038,ASTM D1434.


Application characteristic

High speed vacuum ability, reduce the vacuum time, degassing more thoroughly, high test precision.

Short test time, high efficiency;

Could extend to test bottle, bag;

Power failure protection;

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 proceed 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, easy to grasp the history dynamic of the products.


Product feature

Pure semiconductor cold and hot two-way temperature control, automatically control temperature 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 imported high precision vacuum transducer and pressure sensor.

Embedded system control, using high quality components, ensure stability and reliability of instrument running


 Meeting Standards

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