The model CPE 905 is a miniature combination pH electrode with
internal Ag°/AgCl, 3M Cl- reference element and glass sensing membrane. It is
fabricated from a miniaturized pH sensitive glass bulb which is internally junctioned with
a chloridized, high-purity silver wire immersed in a contacting solution of 3M potassium
chloride that is saturated with silver chloride. The electrode is a compact 6 cm long with
a narrow 2.5 mm O.D. glass barrel and 1.2 mm O.D. pH sensitive tip. Each CPE 905 has a 100 mL reference solution
capacity and a very slow 5 mL/day flow rate. Electrodes are outfitted with BNC connectors that
fit most pH Meters and each is supplied with 25 ml reference filling solution, a filling
capillary, and an instruction sheet.
