3.5.6 Differential potentiometry
Potentiometric measurements with high-ohm measuring chains can be
disrupted by electrostatic and electromagnetic fields in media with low
conductivity. Use our 6.0229.100 Solvotrode or other special electrodes
for pH measurements in organic solvents. If no reliable measurements are
possible with these, then a 6.5104.030 (230 V) or 6.5104.040 (115 V) dif-
ferential amplifier can be used. The differential amplifier is connected to
the high-ohm measuring input (Ind.).
