Manganese Dioxide Electrode

Castle Electrodes RB15 Manganese Dioxide Reference Electrode

General Description

The Castle RB15 Reference Electrode comprises a manganese oxide core containing an alkaline environment. This is contained in a blue nylatron casing with a cementitious mortar cap. The electrode is conditioned to provide a very stable reference electrical potential. The mortar cap ensures good contact with the parent concrete .

Castle RB15 manganese dioxide reference electrodes are connected to a data logger to monitor readings which may be manually downloaded or transmitted remotely via modem to an external ‘off site’ office. Measurements may also be performed by use of a handheld volt meter with high input impedance (>100 M Ω).

The RB15 reference electrode functions as a solid state electrode (no internal gels) and does not require aggressive materials, for example chloride ions, to function. It can be used in most environmental conditions. The side holes in the monitoring tip ensure good contact with the concrete.
