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

KN-5800Z Automatic Lubricating Oil Evaporation Loss Tester (NOACK Test)
The evaporation loss is of particular importance in engine lubrication. Where high temperatures occur, portions of an oil can evaporate.
Evaporation may contribute to oil consumption in an engine and can lead to a change in the properties of an oil. Many engine manufacturers specify a maximum allowable
evaporation loss. Some engine manufacturers, when specifying a maximum
allowable evaporation loss, quote this test method along with the specifications.Read
