Introduction
Put the sample in standard bomb to oxidize,and record pressure according to specified time interval.After certain period,the oxidation degree can be determined by the corresponding decrease of oxygen pressure.This instrument is suitable to determine resistance of lubricating greases to oxidation when stored statically in an oxygen atmosphere in a sealed system at an elevated temperature under conditions of test.
Characteristic
1. Whole test is controlled by computer,no need to watched by man
2. Curve is displayed during test
3. Automatic store result when the test is finished
4. One test bomb can put 5 sample cells
5. The apparatus can check gas leak and alarm automatically
6. Stainless steel electrical heater,heating bath
7. PID program temperature controlling technology,digital display,accuracy±1℃,PT100 sensor
8. 64 bits PIC acquisition card makes sampling and data processing fast
9. LCD interface uses man-machine dialog
10. Alloy steel rack of cell,18% Chromium and 8% niccolum
