MC Miller Reference Electrodes

RE-Series Copper/Copper Sulfate Electrodes The MC Miller "RE" series of electrodes provides three areas of improvement over the electrodes formerly available. These are a Lexan Tube, a CPT ceramic plug, and a strong top cap with a 1/4" high-purity copper rod with 1/4 x 20 external thread and brass knurled nut. The CPT ceramic plugs offer numerous advantages, including: The porosity of the CPT ceramic plug is uniform and controlled.  All ceramic plugs are alike. The CPT ceramic plug is a fast wetting, and the electrode can be used within minutes after filling.  (It often takes many hours to wet up a wood plug). The CPT ceramic plus is pre-treated to provide lower electrical resistance which remains low as long as the plug is moist with saturated copper-sulfate solution. A CPT ceramic plug can become thoroughly dried out, and it will re-wet in a few minutes with the same low resistance.  It is not necessary to keep the electrode in a position where the solution will be in contact with t
