KN-445BZ Semi Automatic Kinematic Viscosity Apparatus
Many petroleum products, and some non-petroleum materials, are used as lubricants, and the correct operation of the equipment depends upon the appropriate viscosity of the liquid being used. In addition, the viscosity of many petroleum fuels is important for the estimation of optimum storage, handling, and operational conditions. Thus, the accurate determination of viscosity is essential to many product specifications.Read

KN-1266 Sulfur Lamp Method Unit
The sample is burned in a closed system, using a suitable lamp (Fig. 1) and an artificial atmosphere composed of
70 % carbon dioxide and 30 % oxygen to prevent formation of nitrogen oxides. The oxides of sulfur are absorbed and oxidized to sulfuric acid by means of hydrogen peroxide solution which is then flushed with air to remove dissolved carbon dioxide. Sulfur as sulfate in the absorbent is determined acidimetrically by titration with standard sodium hydroxide solution, or gravimetrically byRead

KN-4929 Sulfur and Chlorine Microcoulometric Titrator
Injected into quartz tube and mixed with O2, the sample burns .Then the combustion gases are routed into a titration cell and react with I3- or Ag+ . Then the analyzer detects and adds I3- or Ag+ to original concentration. In accordance with Faraday's laws of electrolysis, the detector module calculates energy they consumed and thus gets the concentration of sulfur or chlorine.Read
