Cathodic Disbondment Calomel Reference Electrode

A Refillable glass bodied reference electrode half-cell with a 12mm body designed for use for Cathodic Disbondment testing with 4mm connectors to fit all test rigs and instruments including digital Multi-meters.

The reference electrode is a Calomel system with a ceramic reference junction. The electrode is refillable with E8064 filling solution,

It is common for several tests to be carried out simultaneously. The yellow connector is connected to the yellow sockets on Top-Hex instruments, the black terminal on Multi Meters or the negative terminal on any other Disbondment test instruments.

The EDT directION Calomel Reference electrodes have several advantages over the Ag/AgCl alternatives. Firstly they provide a longer lifetime as the internal solution does not contain Silver Chloride which, in certain applications, and particularly in acid conditions deposits in the reference junction. This reduces flow rate and eventually causes blockage.

It is common when left dry to produce a white crystalline material around the fill hole and tip. This is KCl and can be washed off with water. it is not harmful and will not affect the performance. When not in use the protective cap should be replaced and the fill hole closed.
