HI 4004 Calcium Half-cell

HI 4104 Calcium Combination Electrode

I. Introduction:

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.
