Transmiter 9135 – pH/redox measurement
Page 67
Note :
Note that the impedance measured represents the
sums of the resistances of the "liquid earth"
electrode, reference electrode, glass electrode
according to the case.
In pH measurement in ultra pure water, the very high
resistivity of the sample, does not allow to determine
precisely the reference electrode impedance. In fact,
the liquid impedance is 100 KΩ and represents about
10 times the electrode impedance.
