Reference Electrodes

The cathodic corrosion protection with impressed current anodes has been a proven, excellent method for the protection of units, unit components and constructions against corrosion for many decades now.

Apart from these impressed current anodes (see: "Products" -> PtTi, PtNb, mixed oxide Ti+Nb), METAKEM offers an extensive assortment of reference electrodes:

• Ag/AgCl
• Cu/CuSO₄
• Hg/HgO and Hg/HgSO₄
• Mg- and Zn-half cells

Reference electrodes are suitable for permanent use and therefore have a robust design. They are half cells made of threaded steel connection, a reference unit and a cable/resin connector. Design and construction also allow an easy replacement of the worn or defect parts after several years.

The following elements supplement the product assortment:

• Threaded connections (steel, stainless steel and plastic)
• Welded sockets
• Threaded connections for wire fixing 
• Insulation elements
• Cables

For this area of application METAKEM offers the application-specific design and construction as well as the complete production of pre-finished systems.
