PORTABLE OCTANE METER SX-100M |
Octane Meter is developed in Petroleum Chemisorption Institute of Siberian Branch of Russian Academy of Science. The fuel quality analyzer Octane Meter is intended for evaluation of the type of gasoline, and determination its octane number. The Octane Meter also determines the cetane number of diesel fuel.
Equally good the Octane Meter measures the parameters of the leaded and unleaded gasoline, as well as the gasoline with different additives. 10 seconds is the maximum time to detect the type of gasoline at the worst conditions (cold start). The entire process is automated - the operator only needs to fill the sensor with the gasoline, turn on the instrument, and write down the results from the display.
The Octane Meter is simple in use, and does not require regular adjustments and special maintenance. The use of the Octane Meter eliminates the human factor during the quality estimation of the oil products. It's recommended to use the instrument at petroleum storages, filling stations, customs houses, and for the check of the samples in gasoline production lines.
The measurement principle of the octane level is based on a comparative analysis between the paraMeters of the analyzed gasoline and the reference gasoline paraMeters stored in the microprocessor's memory.
The design of the instrument and the measurement algorithm provides a high-level noise immunity and, as a result, a stable measurement. During gasoline blending octane level can be controlled within the range from 40 to 120. There is an option to adjust the instrument for a nonstandard fuel, for example, natural (gaseous condensate) or virgin gasoline. An advanced user can perform such an adjustment without assistance of the instrument maker.
Note:
Inaccuracy of repeated measurements does not exceed 0.5 unit of octane level.
Absolute error, determined by comparison the Octane Meter indications and indications of stationary instrument in the laboratory environment does not exceed 0.5 unit of octane level.
Octane Meter was registered in public register (N16464-97) and permitted for use in Russian Federation based on the positive results of the tests.
Octane Meter SX-100M in comparison with the base model has: more durable case, more integral parameters of the gasoline and diesel fuel types, four line LCD which displays at the same time the octane number of the analyzed sample by research and motor methods, and temperature of the sample. Cetane number and freezing temperature (as option) is displayed during the analysis of diesel fuel.
Octane Meter SX-100M has 6 modes of operation, 3 of them are general:
1) the base mode, for the determination of the ON of standard gasoline;
2) the mode for the analysis of low octane gasoline produced by blending, and also for gasoline with the 95 octane number;
3) for the analysis of the cetane number of diesel fuel.
Because the octane and cetane number are determined by estimation of integral content of the fuel sample, indications of Octane Meter can be different for two gasoline samples of the same type but produced by different manufacturer. For this Octane Meter SX-100M has 3 additional modes that are analogous with the first three, but are intended for making corrections by the user. At the same time the user corrected algorithm is stored in the memory of octanemeter after it is switched off.
The delivery package of Octane Meter SX-100M consists of the following components:
The electron circuit is made from European and Japanese details. The case of Octane Meter SX-100K and Octane Meter SX-100M is made from shock-proof and gasoline-proof polystyrene. The instrument is powered from AA batteries, and because of low voltage it is electrically safe.

| PORTABLE OCTANE METER SX-100K with RS-232 interface |
Portable octane analyzer is used for instant octane rating of motor gasoline, corresponding to motor and research methods (RON and MON) as well as for cetane number of diesel fuels. In addition for an inquiries, temperature rating of the analyzed liquid and diesel fuel solidification is provided. The results of measuring are displayed on the LCD.
The operational principle of the Octane Meter lies in gasoline octane rating and diesel fuel cetane rating based on the analysis of change of properties of an dielectric permeability and electromagnetic induction.
Octane analyzer has the portable compact design and is used for on-line inspection of motor fuel quality in the field and laboratory conditions. The operating conditions of the Octane analyzer usage: ambient temperature from –10C to +30C, relative humidity 80% at 25 C, atmosphere pressure 84-106kPa. The device gets power from DC elements of type AA (supply voltage 6V).
The delivery package of Octane Meter SX-100K consists of the following components:
You can take measurements and make the measurement table in txt or xls format which include the information about sample at the same time;
The correction of the measurment become much easier;
The information about the work of octane tester, correction, and measurment data are display on the screen of the computer.
