Connection of electrodes and temperature sensor
• 2 high-impedance measuring inputs for pH and U measurements (Ind I/ Ind II).
They can either be used separately or for differential potentiometry, see page
124.
Important: If you work with both measuring inputs in the same vessel, the same
reference electrode must be used.
• 1 measuring input for polarized electrodes (Pol).
• 1 measuring input for PT100 or Pt1000 temperature sensor.
