Description

Sea Water – Tidal Basin – Marsh Land – Concrete

dvantages

  • Combination Kit contains 8-foot submersible adapter with longer lengths available.
  • The Ag / AgCl electrode is an ideal reference electrode for high chloride content applications
Applications

 

  • Sea Water
  • Tidal Basin
  • Marsh Land
  • Concrete
 

 

The sea water Kit is used in conjunction with an M. C. Miller Co., Inc. submersible adapter to measure the cathodic protection potentials. The sea water in which the electrode is immersed is the electrolyte. The Seawater electrode (half-cell) potential is a function of the salinity of the electrolyte into which the electrode is immersed. Please see “A Guide to Understanding Reference Electrode Readings”.

 

 

The Land Kit is supplied with a standard filling solution (3.5 M KCl), which acts as the electrolyte. This is a known electrolyte which can be used where the salinity of the sea water is unknown, as in brackish, fresh water / sea inlets. This is ideally suited for areas where chlorides would contaminate the Standard copper sulfate electrode. These areas would include concrete bridge decks (de-icing salts), swamps and marsh lands.
