EMS Mendeleevets - Portable copper-sulphate electrode
Application area
The copper-sulfate electrode for electrometric measurements EMS Mendeleevets is intended for use as a portable reference electrode when measuring the potential difference between an underground construction protected by the cathodic polarization, and ground. The electrode is designed for operation in all climatic conditions with ambient temperature from -5 to +45 °C.
Technical details
Рic. 1. Types of tips:
a – cone;
b – plug
The EMS electrodes are produced of two types: EMS-0,4 – with a short handle (is used as a stationary electrode) and electrode EMS-1,2 – with a full-sized handle (for intensive measurements).
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 wire is brought from the reference electrode to the plug located on the handle under the rubber handle.
- The EMS electrodes are completed with two types of tips:
- in a form of a cone – for measurements in soft grounds (Pic. 1a);
- in the form of a flat plug – for measurements in solid grounds (Pic. 1b).
