I. Introduction:

Introduction:

The Hanna HI 4012 and HI 4112 are ion selective elec-
trodes designed for the measurement of Lead ions in
aqueous solutions. The HI 4012 is a solid state half-cell
sensor that requires a separate reference. The HI 4112 is a
combination ion selective electrode.

Specifications

Type:

Solid State electrode with
a lead sulfide pellet.

Ion(s) measured:

Lead (Pb

)

Measurement range: 0.1

M to 1X 10

-6

20700 to 0.21 ppm

Interfering ions:

Silver, Copper, Cadmium

Iron (2+ 3+) and Mercury must be absent. Any ion that
forms a more insoluble sulfide than lead sulfide will interfere
with the electrode response. Long term exposure in this ion
will poison the lead surface. Oxidation of the lead surface
will also poison the electrode.

Operating Temperature:

0-80

°C

Operating pH:

4 to 7 pH
(recommended)

Dimensions:

12 mm (OD) X 120 mm
nominal insertion
(0.47

” X 4.72”)

Connection:

BNC
