measuring range that can be enlarged.

Test principles

N 530 Gas Permeation Analyzer designed using the principle of differential pressure method, preparation 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.

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. Seperately 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 independently, 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

13. Software interface is simple and easy to operate, automatically save the test report can be printed and other parameters and the transmittance curve of the report.

14. Optional pairs of air humidity controlling devices, more precise of

controlling wet;

15. Calibration method of standard film
