Octane Number & Cetane Number Tester (Desktop)

Summary

  SYD-QX-G Octane number & cetane number tester is our company's new product. It is suitable to determine the octane number number of aviation gasoline, motor gasoline, blended gasoline, ethanol gasoline, and it is also suitable to determine the cetane number of automobile diesel fuels. It’s dual-use and meets the international standards to determine fast.

I.    Main technical characteristics

1.With the innovative high precision digital sensor, strong anti-interference capability, less deviation, high precision, good reproducibility and repeatability.

2.With the automatic returning technical platform to realize the value transformation from the national standard CFR tester to SYD-QX-G and be geared with the China standard GB/T5487 and ASTM D2699, improve the measurement accuracy and expand the measurement range.

3.Establishing the technical platform to jointly do the auxiliary calculation with the traditional petroleum detecting instruments (Distillation tester, Densimeter), it makes sure that the cetane index of diesel fuels and the cetane number be measured more accurately, and could gear with the technical requirements GB/T386.

4.It adopts the color LCD touch display, with simple and convenient man-machine conversation screen, and guide the user to operate correctly according to the hints on the screen display.

5. It adopts automatic value assignment calibration technology. The calibration procedure is simple, the method is scientific, and the calibration result is accurate and reliable.

6. Gasoline octane number test: A test can display research octane number, motor octane number and antiknock index at the same time. Diesel fuels test can display the cetane number, to input standard density and mid-boiling point can get cetane index, to derive the correct the cetane number automatically.

7. It needs less test oil, every test only needs 150 ml samples; The test time is short, every test time is in 1 min.
