Product Description

Item: Gas (oxygen) Permeation Rate Tester  in Plastic Film 
Model: DPG-V1

Product function:
It is applied to various gas permeation rate detection, such as 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 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;
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.
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 D1434,ISO 2556,ISO 15105-1,JIS K7126-A,YBB 00082003
