Product Description
ST-13A Automatic Potentiometric Titrator
The ST-13A automatic potentiometric titrator is designed according to GB5009.229-2016 "Determination of Acid Value in Foods" (cold solvent automatic potentiometric titration method) and GB5009.227-2023 "Determination of Peroxide Value in Foods" standards. This instrument uses potentiometric titration to automatically distinguish the titration endpoint and calculate results, making it suitable for determining acid values in various food samples including edible oils.
Instrument Features
  • Universal microcomputer operating system with Windows 10 interface
  • Human-machine dialogue mode operation with clear, simple steps
  • Chinese window interface software operated by mouse and keyboard
  • Real-time display of potential curve (E-V), first derivative curve (dE/dV), electrode potential (E), titration volume (V), and titration results
  • Full process titration data browsing with powerful data processing capabilities
  • Results, data, and curves stored in large quantities
  • Titration process data can be saved as Excel documents
  • Automatic printing of curves, results, and titration data
  • Multiple titration modes: Dynamic Equivalent Point Titration (DET), Equivalent Equivalent Point Titration (MET), Pre-set Endpoint Potential Titration (SET)
  • Fully automatic endpoint discrimination with false endpoint filtering
  • Automatic cleaning, fluid replenishment, and constant liquid addition
