The Deepwater Polatrak DR-2 is a rugged dual-element reference electrode designed to provide CP status for 20 years. Hundreds of these electrodes are in reliable service all over the world.

The current DR-2 has an improved machined black Delrin body, which enhances the impact resistance of the assembled instrument.

A sintered Ag/AgCl reference electrode provides very accurate potential data to monitor polarization of the structure. A heavy-duty zinc electrode element serves as a long-term, ultra-reliable, low-resolution electrode.

The dual-element (Ag/AgCl sw / Zinc) reference electrode is designed for weld-on, bolt-on or clamp-on attachment to an offshore structure.

Designed for permanent monitoring of cathodic protection systems, the electrode has a 20-year design life. Added to the back of the instrument is a 10 square foot current density monitoring array, such that polarization data may be logged directly from the instrument.

Available remote control monitoring systems are standard on new structures. Polatrak systems give you the option to tie into communication lines, providing remote cathodic protection monitoring over existing infrastructure.
