ASTM D189 Conradson Carbon Residue Tester
KN-189 Conradson Carbon Residue Tester conforms to ASTM D189 Standard Test Method for Conradson Carbon Residue of Petroleum Products. This apparatus covers the determination of the amount of carbon residue left after evaporation and pyrolysis of an oil, and is intended to provide some indication of relative coke-forming propensities. This test method is generally applicable to relatively nonvolatile petroleum products which partially decompose on distillation at atmospheric pressure, our KN-189 Provides an indication of relative coke forming properties of petroleum oils. The residue remaining after a specified period of evaporation and pyrolysis is calculated as a percentage of the original sample.

Relative Scuffing Load Carrying Capacity Tester, FZG
KN-FZG Relative Scuffing Load Carrying Capacity Tester conforms to ISO 14635-1 Gears – FZG test procedures—Part 1: FZG test method A/8, 3/90 for relative scuffing load-carrying capacity of oils and ISO 14635-2 – FZG test method A10/16,6R/90 for relative scuffing load-carrying capacity of lubricants with high EP performance. The types of gear failures which may be influenced by the lubricant in use are scuffing, low-speed wear and the gear-surface fatigue phenomena known as micropitting and pitting. In the gear design process, these gear damages are taken into consideration by the use of specific lubricant and service-related characteristic values. For an accurate, field-related selection of these values, adequate lubricant test procedures are required. The FZG test procedures described in this and other parts of ISO 14635 can be regarded as tools for the determination of the lubricant-related characteristic values to be introduced into the load-carrying capacity calculation of gears.

Reid Vapor Pressure Bath
KN-323 Reid Vapor Pressure Bath conforms to ASTM D323 Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method). It used for testing the vapor pressure (Because the external atmospheric pressure is counteracted by the atmospheric pressure initially present in the vapor chamber, the Reid vapor pressure is an absolute pressure at 37.8°C (100°F) in kilopascals (pounds-force per square inch)

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.
