KN-92Z Automatic Cleveland Open Cup Flash Point Tester
Flash point can indicate the possible presence of highly volatile and flammable materials in a relatively nonvolatile or nonflammable material. For example, an abnormally low flash point on a test specimen of engine oil can indicate gasoline contaminationRead

KN-1160 Vacuum Distillation Apparatus
The sample is distilled at an accurately controlled pressure between 0.13 and 6.7 kPa (1 and 50 mm Hg) under conditions that are designed to provide approximately one theoretical plate fractionation. Data are obtained from which the initial boiling point, the final boiling point, and a distillation curve relating volume percent distilled and atmospheric equivalent boiling point temperature can be prepared.Read

KN-4006A Water in Crude Oil Apparatus (Distillation Method)
The sample is heated under reflux conditions with a water immiscible solvent which co-distills with the water in the sample. Condensed solvent and water are continuously separated in a trap—the water settles in the graduated section of the trap, and the solvent returns to the distillation flaskRead

KN-6304 Coulometric Karl-Fischer Titration Tester
A knowledge of the water content of lubricating oils, additives, and similar products is important in the manufacturing, purchase, sale, or transfer of such petroleum products to help in predicting their quality and performance characteristicsRead

KN-203 Volumetric Karl Fischer Moisture Titrator
although the volumetric KF titration can determine low levels of water,it is generally accepted that coumometric KF titrations are more accurate for routine determination of very low levels of water. as a general rule, if samples routinely contain water concentrations of 500Mg/kg or less,the coumometric tech should be considered.Read

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
