SM23 single pNa electrode
The SM23 is suitable for long term, reliable Sodium ion
monitoring, Another application is to use the pNa sensor as
reference electrode for pH measeurement in combination with
and analyzer with dual high input impedance specification. 
This may considerably save maintenance costs in application
where the salt content is constant and pH>pNa+2.
pNa measurement is used in many applications, but the most
frequent applications are found in pure water applications, 
where Sodium is measured to detect carry-over of salts in steam,
leakage of salt through cation filters, Leakage of salt from leaking
condensers.
Other applications where the pNa electrode is used for
measurement is in brine solutions. Please note that accurate
measurement requires that the pH is 2-3 units higher 
than the pNa value.
