Power Plant
Stable pH reading in low conductivity and ion weak samples are typically difficult to achieve. Hamilton offers 3 types of sensors for these difficult conditions.




Cation Exchanger


Cation exchange is done to keep the quality of the boiler feed water up, i.e., the conductivity and salt content low to prevent corrosion and clogging.


Sensors and Conditions



pH Sensors for Cation Exchanger



Goal of Measurement:
N/A

Range: Resolution: Interference: Sensor Type: Armatures:
N/A N/A None -- --
         
Other Conditions: Applications: Benefit of Sensor:
None N/A Very low conductivity, pH is calculated indirectly from decrease of conductivity after cation exchange.



Conductivity Sensors for Cation Exchanger



Goal of Measurement:
To monitor the success of ion exchange. Conductivity is measured before and after ion exchange to calculate cation conductivity and indirect pH.
