I. I. I. I. I. Introduction: Introduction: Introduction: Introduction: Introduction:
The Hanna HI 4003 and HI 4103 are ion selective elec-
trodes designed for the measurement of cadmium ions in
aqueous solutions. The HI 4003 is a solid state half-cell
sensor that requires a separate reference. The HI 4103 is a
combination ion selective electrode.

Type: Solid State electrode with
a Cadmium sulfide/ silver
sulfide membrane.
Ion(s) measured: Cadmium (Cd
2+ + + + +
)
Measurement range: 0.1 M to 1X 10 -7 M
11,200 to 0.01 ppm
Interfering ions: Silver and mercury must
be absent. Any ion that forms a more insoluble sulfide than
cadmium sulfide will interfere with the electrode response.
These include lead (Pb
2+
)and cupric ions (Cu
2+
). Oxidation
of the cadmium surface by ferric ion( Fe
3+
) will severely
poison the electrode. Ions that can form complexes with
cadmium ions will reduce the measured concentration.
Examples include bromide, chloride and EDTA.
Operating Temperature: 0-80 °C
Operating pH: 2 to12 pH
concentration dependant
(4.5-7.5 recommended)
Dimensions: 12 mm (OD) X 120 mm
nominal insertion
