SHATOX SX-300 Petroleum Quality Analyzer

New oil products grade analyzer is manufactured on the basis of advanced high precision microprocessor. The instrument can be used together with a PC or laptop through USB interface. Analyzer uses automatic computer-based calibration, saving measured data in the instrument memory with analysis date and time followed by their transfer to the PC (in Microsoft Excel or txt format). The instrument has easy of control attrition and aggressive environments resistive 8-key antiglare keyboard (made in Germany).

Analyzer SX-300 has a distinctive characteristic, an additional sensor, which measures oil products volume resistivity with high precision. Therefore, fuel analysis may be based on two values, which allows measuring octane number of petrols with ferriferous (ferrocene), nickel and manganese additives, and to determine other substances content.
By using this measurement principle the instrument allows to determine:

  • contamination content in oil products;
  • pour-point depressants content in diesel fuel;
  • engine oil base number;
  • oil products volume resistivity.

When determining petrol breakdown time, the petrol brand is selected in the instrument. The instrument switches to corresponding operating mode. Oxidative stability determination complies with GOST 4039-88 (ASTM D 525)

Motor oil brand identification is based on the permittivity determination principle. Genuine motor oils have certain value for this characteristic. Leading manufacturers’ oil brands are included into the instrument database (the database can be renewed or changed).

Water-in-oil percentage of oil and oil products is determined in compliance with GOST 14203-69 (Dielectric humidity measuring method). This allows using the instrument as a dielectric moisture indicator for oil products.

The instrument uses the timer microchip, which allows storing measurement results with analysis date and time. These data can also be transmitted to the computer.

New computer software is included into the set.
- measurement results are reflected on computer screen in convenient form;
