Polatrak® DC II™ DROP CELL w/500 FT CABLE

One Polatrak DC-II drop-cell probe with 500 feet of cable and high-capacity reel; extra cable lengths up to 1,500 feet are available for additional cost.

DC II™ with 500 feet of cable

The Polatrak DC II is the first and only twin-element portable reference electrode of its kind. The twin elements provide on-board calibration, which reduces the chances of topside survey inaccuracies. The DC II boasts a guaranteed accuracy of +/- 5 mV. Trips offshore are expensive, and faulty equipment should never be a reason for repeating a mobilization.

The rugged thermoplastic housing and tapered cone prevents snagging. The DC II shown is available with extra-long, three-conductor, 180” O.D. high-strength cable (up to 1,500 feet) and a high-capacity cable reel. The standard model comes with 250 feet (75 m) of cable.
