Octane Number & Cetane Number Tester

 SYD-QX-D Octane number & cetane number tester is our company's new product. It is suitable to determine the octane number and cetane number of aviation gasoline, gasoline for motor vehicles, blended gasoline, ethanol gasoline, Methanol gasoline, automobile diesel fuels.

I. Main technical features

1.It adopts high precision test sensor, comprehensive analysis of large data, advanced calculation methods, the test result of gasoline octane number meets the requirement of GB/T 5487, GB/T 503 and ASTM D2699-86, the test result of diesel fuels meets the requirement of GB/T 386.

2.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.

3.The sensor signal adopts digital transmission technology, powerful anti-jamming performance, small variation, high precision, good reproducibility and repeatability.

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