Ion-selective electrodes are responsive to the concentration of particular ions in the test liquid and are variable-potential electrodes. They are used in conjunction with reference electrodes to measure the concentration of particular ions. HORIBA’s years of experience and know-how in this field are behind the wide range of ion electrodes we offer. When measurements are made using an ion meter, calibrating it with various standard solutions will give direct readings of the ion concentration.
