The principle of the octane number / cetane number tester is to measure the insulation permeability and electromagnetic induction charge characteristics of the octane number of gasoline and the cetane number of diesel. By measuring the dielectric properties of the oil and comparing it with the known data stored in the memory, the result can be determined. The sensing device is very accurate and can measure tiny changes in dielectric parameters. So it is a very good choice to detect petroleum product parameters such as octane number and cetane number.
