The potential of each electrode is measured relative to a fixed, stable 
voltage established by the double-junction silver/silver chloride refer-
ence electrode. An ion selective electrode develops a voltage that varies 
with the concentration of the ion to which it responds. The relationship 
between the voltage developed and the concentration of the sensed ion 
is logarithmic, as expressed by the Nernst equation.

Nernst equation:

nF

E 

=  E° +  RT Log (

γ

 C)

where:
 

E  =  The potential of the sensor in sample solution

 

E°  =  The potential developed under standard conditions

  RT/nF  =  A temperature-dependent “constant” termed the slope, S
 

n  =  1 for sodium and potassium; 2 for calcium 

 

Log  =  Base ten logarithm function

 

γ

  =  Activity coefficient of the measured ion in the solution

 

C  = Concentration of the measured ion in the solution
