Automatic determination of SO2 by potentiometry

This apparatus is designed to quickly and easily measure free and total SO2 by eliminating the difficult determination of the end of the measure. The Iodolyser is particularly adapted to highly colored red wines, lees for distillation, fruit juices, alcoholic drinks, and vinegars.

  • 119650-Iodolyser - automatic determination of SO2


With a double platinum electrode which detects an electric current in the sample, the Iodolyser carries out the titration and stops automatically when the oxidizing solution of Iodide/Iodate is in excess. The apparatus calculates the result according to the selected program (free or total SO2) and displays it immediately on the screen.


  • Direct display of the result on LCD screen
  • Quick and easy to use
  • Ergonomic and aesthetic conception
  • Excellent repeatability
  • Linear guidance of the support of the agitator and the probe
  • Magnetic stirrer 
  • Automatic titration with a syringe pump activated by a stepper 
  • Automatic self-zeroing of the syringe between analyses 
  • Readouts identified by date and hour


  • Sample type: red wines, lees for distillation, fruit juices, alcoholic drinks, vinegars.
  • Measurement scale: 0-200 mg/L of free SO2 and 0-500 mg/L of total SO2
