EMS-VE Mendeleevets - EMS with an auxiliary electrode
Application area
A copper-sulfate electrode with an auxiliary electrode EMS-VE Mendeleevets is intended for use as a portable reference electrode for measurements of the protective (total) and polarization (in accordance with GOST 9.602- 2005) potentials of underground construction which is under the action of cathodic protection. The electrode is designed for operation in all climatic conditions with ambient temperature from -5 to +45 °C.
Technical details
The electrode is produced in accordance with the Manual for corrosion protection systems of pipelines.
The EMS-VE electrode design is similar to that of EMS electrode. An auxiliary electrode of ring form is fixed on the measuring body of a copper-sulfate electrode and equipped with own conductor.
For simplification of a design and convenience of operation the handle of the EMS electrode is made of dural tube ending with a rubber handle. The measuring wires are brought from the reference electrode and the auxiliary electrode to the marked plugs located on the handle under the rubber handle.
The EMS-VE electrode can be used with such devices as IPP-1, Diacor and others.
