Product Description

Product description

     Whether in the field or in the laboratory,this analyzers are leaders in portable rapid analysis instruments. We designs and produces analytical instruments for gasoline, diesel, motor oil and transformer oil.

    Portable octane and cetane 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.

Octane and cetane 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.

 

Function

1. Determining octane numbers for motor petrols;

2. Determining cetane numbers for diesel fuels;

3. Determining solidification temperature and diesel fuel type;

4. Content of antiknock compounds boosting the octane number of petrols;

5. Content of pour-point depressants for diesel fuels;

6. Content of kerosine in summer diesel fuel;

7. Petrol breakdown time (oxidative stability);

8. Loss angle tangent of circuit-breaker, machine and engine oil;

9. Level of engine, machine and circuit-breaker oil clarity;

10. Manufacturer, engine oil brand;

11. Engine oil base number;

12. Dielectric permeability of oil products;

13. Oil products volume resistivity;

14. Determining the mechanical impurities content in oil products;

15. Determining the cut. GOST 14203-69 – Oil and oil products. Dielectric humidity measuring method.

 

Measuring principle

The principle of Octane Meter operation is in determining knock characteristic of gasoline, self-flammability of diesel fuel and in determining oil characteristics based on measurements of its dielectric permeability and volume resistivity.
