Portable Octane and Cetane Meter SX-150,SX-300
Product description
Portable octane analyzers are often used for on-site analysis of octane number of power gasoline, corresponding to the motor method and research method (RON and MON), and also suitable for cetane number analysis of diesel. In addition, the temperature of the analyzed liquid and the freezing point of diesel can also be measured, and the measurement results are displayed on the LCD liquid crystal display.
This octane analyzer is widely used all over the world. Its measurement method conforms to international standards: octane measurement conforms to: ASTM D 2699-86, ASTM D 2700-86. Diesel cetane measurement conforms to: ASTM D 4737- 03, ASTM D 613, EN ISO 5165.
Measuring principle
The principle of the TP-150 octane cetane number tester lies in the analysis of the insulation permeability of the octane number of gasoline and the cetane number of diesel oil and the charge characteristics of electromagnetic induction. By measuring the dielectric properties of the sample and comparing with the known parameters in the memory, the result is determined. The instrument is very sensitive and can measure small changes in dielectric parameters. It can detect octane number, cetane number and other petroleum product parameters.
