1. The instrument adopts high-precision digital sensors, which have strong anti-interference ability, small variation, and high precision; The reproducibility and repeatability are very good.

2. The instrument is equipped with an automatic regression technology platform, which enables the transfer of measurement values from the CFR testing machine specified by the national standard to this instrument, and also achieves alignment with the national standard GB/T5487. Improved measurement accuracy and expanded measurement range, laying a solid foundation for users to develop their own measurement projects.

3. It can be combined with traditional oil detection equipment (distillation range meter, density meter) to provide an auxiliary calculation technology platform by inputting two sets of data, making the determination of diesel cetane index and cetane number more accurate and in line with the technical requirements of GB/T386.

4. Adopting a color touch screen operation mode, the human-machine dialogue is simple, friendly, and convenient. According to the screen display, it can guide users to operate the instrument correctly, greatly improving the technical content of the instrument.

5. The application of automatic assignment calibration technology has simple calibration procedures, scientific methods, and accurate and reliable calibration results. Regular maintenance and calibration by users can ensure the long-term accuracy and reliability of the instrument.

6. Determination of gasoline octane number, one measurement can simultaneously obtain research octane number, motor octane number, and anti knock index (one screen, three displays); The determination of diesel cetane number directly displays the cetane number; By entering the standard density and boiling point, the cetane index can be obtained, and the accurate cetane number will be automatically exported (displayed on one screen with two screens).

7. This instrument uses less oil sample for measurement, with only 150ml of sample used for each measurement; The measurement time is short, and each measurement is completed within 1 minute.
