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.

Specifications

Type: Solid State electrode with

a Cadmium sulfide/ silver

sulfide membrane.

Ion(s) measured: Cadmium (Cd

)

Measurement range: 0.1

M to 1X 10

-7

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

)and cupric ions (Cu

). Oxidation

of the cadmium surface by ferric ion( Fe

) 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

(0.47” X 4.72”)

Connection: BNC
