Comparison electrode copper sulfate stationary gel frost-resistant

Abstract

The utility model relates to devices for corrosion measurement systems on steel underground structures for determining the danger of electrochemical corrosion and monitoring the effectiveness of electrochemical protection, in particular to stationary copper sulfate reference electrodes. The technical result of the utility model is to ensure the possibility of storing, transporting and using the electrode at temperatures ranging from minus 30°C to plus 50°C while maintaining its operational characteristics, as well as increasing the service life of the electrode by reducing electrolyte leakage, maintaining the moisture content of the gel-like electrolyte and maintaining its structural stability at elevated temperatures. This is achieved by the fact that the portable copper sulfate reference electrode, according to the utility model, is filled with a gel-like frost-resistant electrolyte containing an aqueous phase, a copper salt, an antifreeze additive, a sulfuric acid solution, a water-soluble polymer thickener, a rheological modifier and a dispersed structure-forming filler, and the electrode body is made of heat-stable impact-resistant plastic, ensuring the stability of the structure during operation at low temperatures.
