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.
