The Polatrak® DC II™ is the first and only twin-element portable reference electrode of its kind.
The DC II™ is used to survey more offshore structures worldwide than any other portable drop-cell-style cathodic protection probe, and has been specified by a large number of operators as the only acceptable choice of equipment. Twin elements provide on-board calibration, reducing the chances of topside survey inaccuracies.

Guaranteed accuracy
Twin Ag/AgCl electrodes provide internal redundancy and on-line calibration, allowing the inspector to verify readings in real time. The DC II™ boasts guaranteed accuracy of +/- 5 mV.

Rugged construction
The rugged thermoplastic housing and tapered cone prevents snagging, and the high-strength conductor cable is suitable for the harshest offshore environments.
