    an electronic way to test my water hardness using potassium instead of salt

    I was looking for a hardness tester and across a Hanna Instruments HI98202
    and looking at the manual and it says it tests hardness by
    the pNa tester utilizes a sodium ion-selective
    electrode to determine the activity of free sodium
    in solution.

    Since it determines the activity of free sodium in a solution does using potassium still make the tester give the same reading as using salt ?
