Description
The ElectroTechCP? ERE 20 Reference
Electrode is used for controlling correct operation and monitoring corrosion
conditions for cathodic protection systems installed in reinforced concrete
structures. The ERE 20 contains manganese dioxide in a very alkaline
electrolyte gel. The reference electrode measures the potential difference
between the electrolyte and the reinforcing steel. The manganese dioxide is
placed in a stainless-steel capsule along with the electrolyte and is enclosed
by an ion exchange membrane of cement mortar. The capsule is sealed with mastic
and heat shrink tubing, insuring that the contents do not escape. In order to
protect the membrane and keep it moisturized, a wetted sponge is placed inside
the protective cap. The cap must be removed before installation. The half-cell
reaction can be measured through a data logger which enables remote
surveillance of the system. Alternatively, a regular handheld voltmeter with a
high input impedance can be used to perform the measurements. The electrode is
suitable for monitoring cathodic protection following the EN 12696 standards
Features and Benefits
- Due to the amount of cell
electrolytes a long service life is assured
- May easily be embedded in new
or old concrete structures as the installation can be performed gently
- Good affinity to the concrete due
to the cement mortar membrane
- Remote surveillance possible
through a modem
- Can sustain environments with
levels of carbonization and may be exposed to chlorides as it is nearly
independent of changes in the chemical properties of the concrete
