Description

The SOLLICH 1503 CATHODIC PROTECTION MICROSTATION  is a device intended for the cathodic protection of metal and reinforced concrete structures. This protection consists in providing the appropriate protection potential of the structure by forcing current in the anode system – a protected construction.

The SOLLICH 1503 CATHODIC PROTECTION MICROSTATION device works in a two-electrode system – without a reference electrode, or a three-electrode system in combination with a reference electrode.

The device enables programming the value of the polarization current Ip (cathodic protection current) or the turn-on potential Eon or turn-off potential Eoff, relative to the reference electrode Eo (measuring) and maintains these values during operation.

The device measures the value of the polarization current (cathodic protection) Ip, the turn-on potential Eon or turn-off potential Eoff relative to the reference electrode Eo, and the anode-cathode voltage Ua.

The station can operate without forced cooling in ambient temperatures up to 50 °C.

Device functions
