Introduction:

The Hanna HI 4004 and HI 4104 are ion selective elec-

trodes designed for the measurement of calcium ions in

aqueous solutions. They utilize a replaceable sensing mod-

ule that contains an organic polymer membrane that is

sensitive to calcium ions. The HI 4004 is a half-cell elec-

trode that requires a separate reference. The HI 4104 is a

combination ion selective electrode.
