HI 4013 Nitrate Half-cell

HI 4113 Nitrate Combination Electrode

I. Introduction:

Introduction:

The Hanna HI 4013 and HI 4113 are ion selective elec-
trodes designed for the measurement of nitrate ions in
aqueous solutions. They utilize a replaceable sensing mod-
ule that contains an organic polymer membrane that is
sensitive to nitrate ions. The HI 4013 is a half-cell electrode
that requires a separate reference. The HI 4113 is a combi-
nation ion selective electrode.
