Thekey differencebetween pH meter and potentiometer is that thepH meter measures the hydrogen ion activity in aqueous solutions, whereas the potentiometer measures the voltage by comparing an unknown voltage to
while potentiometers are typically used for low-power applications where voltage division or signal control is required, and precision control is desired. However, the specific choice between a rheostat and a potentiometer will depend on the requirements of your particular circuit and the parameters...
