Detail Automatic Potentiometric Titrator

Automatic Potentiometric Titrator

For determination of Total Acid Number (TAN), Total Base Number (TBN), Mercaptan Sulfur and Karl Fischer Water Content of petroleum products, lubricants and transformer insulating oils. Titration is the fundamental chemical analysis procedure whereby the concentration of a chemical substance in solution is determined by reacting it with a measured amount of another chemical. The Auto titrator performs this analysis using a motor driven dispenser, stirred reaction vessel and electrodes which sense the completion of reaction by measuring the potential difference between two electrodes. Automatic Titration increases accuracy, repeatability and reproducibility as well as minimizing errors in calculation and documentation.

  • Acid-base or aqueous titration
  • Redox titration
  • Complexometric titration or EDTA titration
  •  Blank titration
  • Silver Assay titrations
  • Non-aqueous titration
  • Argentometric or Precipitation titration
  • Voltametric / KF Titration
  • Back titration
The Automatic Titrator is provided with two-point auto calibration and standardization (zero offset). The instrument is capable of displaying pH and mV of the sample, with temperature compensation. The Automatic Titrator can accept a variety of electrodes to cater to various applications in different fields. The liquid path is comprised of Teflon tubing, a Teflon lined valve and gas tight burette with a Teflon plunger head. It creates a chemically inert system for any sensitive analysis. The instrument is supplied with high speed vortex stirrer with digital speed indication. This specially designed stirrer provides excellent homogenous mixing of samples. An optional magnetic stirrer is also available
