A Microprocessor-controlled Potentiometric Titrator
A typical instrument (Figure 13.6) will have a certain amount of memory for the storage of methods and
data, and will offer a choice of several modes of titration, e.g.
- incremental (pre-selected increments and time intervals)
- equilibrium (pre-selected increments at variable time intervals)
- end-point (pre determined end point in mV or pX)
- recording (continuous, curve drawn on chart recorder).
