OVERVIEW
Gas Permeation Testing Equipment
adopts the principle of the pressure difference to measure the permeability of gas.
Gas Permeation Analyzer
model N530 is for the detection of gas permeability of various films, infusion bags and other packaging materials for O2, CO2, N2 and other gases through the barrier properties. It is designed and manufactured according to the standards of ISO 2556-2001, ISO15105-1, GB / T 1038-2000, ASTM D1434-82 (2003), YBB00082003...It has three independent testing chambers and independent temperature control system. The core is connected with computer through the USB. It can automatically judge and stop testing. The testing result is stable, curves of permeability, temperature, pressure will be shown at the same time. The test report will generate automatically while the data automatically stored. It also support TCP/IP protocol. There are three measuring range that can be enlarged.
Test principle
N 530 Gas Permeation Analyzer designed using the principle of differential pressure method, preperation samples will be placed between in the test chamber with high / low pressure, and clamping it, then make the whole test system to have a vacuum processed, input test gas the high-pressure test chamber to ensure on both sides of the test samples have a constant pressure, the gas under the role of pressure pass through film from high-pressure chamber to the low pressure chamber to infiltrate, observe the changes pressure in low-pressure chamber to caculate barrier parameters of the sample.

Features
1. Computer automatically control three chambers of testing, can test different samples, Configuration three independent sensors, each chamber can be set different temperatures. First creating positive and negative pressure dual-mode testing, leading international standard.
2. The sample can be tested by single chamber, or double chambers or three chambers.
3. Indepently show the curve of transmission, pressure, pressure value and temperature.
4. High or low levels of barrier test, repeat excellent performance.
5. The international advanced electromagnetic process step temperature control technology, ease lifting the temperature, variable temperature adjustable-rate, temperature control accuracy of ± 0.01 range.
6. High and low resistance, two kinds of test mode
7. Excellent test reproducibility.
8. An excellent environmental adaptability, no special requirements on the environment.
9. Real-time display of each point transmission, through the transmittance curve, can understand the testing process.
10. The curves of each chamber's temperature, humidity, weight, and transmission display indepently, continous to display four- groups-curve, can monitor the interaction of parameters at the same time.
11. Software interface is simple and easy to operate, automatically test.
12. Overpressure protection
