Working principle

Basic working principle: The instrument uses the dielectric constant method to determine the octane number of gasoline.

The method is to use mathematical statistics to process a large amount of experimental data, obtain the correlation between gasoline octane number and dielectric constant, and determine gasoline octane number by measuring the dielectric constant of gasoline. 2. Based on rigorous mathematical models and using the measurement results of the CFR testing machine as the standard, automatic regression is performed. To achieve the goal of improving measurement accuracy. The combination of two methods ultimately achieves the determination of gasoline octane number by measuring the dielectric constant of gasoline* The first method is the foundation, but the determination of the second method is more accurate and scientific.
The instrument consists of electronic instruments and sensors. The signals collected by sensors are converted into pulse digital signals and transmitted to electronic instruments in an active low impedance high amplitude manner. After processing by the CPU, the measurement results are displayed. And it can be browsed and printed.
