1.1.2 Titration and measuring modes
The following titration and measuring modes are supported:
￭ DET
Dynamic equivalence point titration. The reagent is added in variable
volume steps.
Measuring modes:
– pH (potentiometric pH measurement)
– U (potentiometric voltage measurement)
– Ipol (voltametric measurement with adjustable polarization cur-
rent)
– Upol (amperometric measurement with adjustable polarization
voltage)
￭ MET
Monotonic equivalence point titration. The reagent is added in con-
stant volume steps.
Measuring modes:
– pH (potentiometric pH measurement)
– U (potentiometric voltage measurement)
– Ipol (voltametric measurement with adjustable polarization cur-
rent)
– Upol (amperometric measurement with adjustable polarization
voltage)
￭ SET
Endpoint titration at one or two specified endpoints.
Measuring modes:
– pH (potentiometric pH measurement)
– U (potentiometric voltage measurement)
– Ipol (voltametric measurement with adjustable polarization cur-
rent)
– Upol (amperometric measurement with adjustable polarization
voltage)
￭ CAL
Electrode calibration.
Measuring mode:
– pH (calibration of pH electrodes)
1.1.3 Intended use
The 862 Compact Titrosampler is designed for usage as an automation
system in analytical laboratories. It is not suitable for usage in biochemi-
cal, biological or medical environments in its basic equipment version.
This instrument is suitable for dosing chemicals and flammable solvents.
The usage of the 862 Compact Titrosampler therefore requires that the
user has basic knowledge and experience in the handling of toxic and
caustic substances. Knowledge with respect to the application of the fire
