SX-250 Portable Octane and Cetane Analyzer

New oil products grade analyzer is manufactured on the basis of advanced high precision microprocessor. This model is designed for the operation with fuels and oils. It continues the series "2xx" (fuel and oil quality analysis). Additionally, SX-250 has the mode for determining the purity of mineral, synthetic, industrial oils, the mode for measuring dielectric permeability of oil products, as well as the mode for determining water content in diesel. The instrument can be used together with a PC a 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). 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). 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.
