face="Verdana" size="1">The model CPE 905 is a miniature combination pH electrode with
internal Ag�/AgCl, 3M Cl<sup>-</sup> 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</font><font

capacity and a very slow 5 </font><font size="1" face="Symbol">m</font><font

fit most pH Meters and each is supplied with 25 ml reference filling solution, a filling
capillary, and an instruction sheet.<o:p></o:p></font></td>
