Description
A single set of disposable alkaline batteries provides up to 150 hours of survey operation. A convenient on-off switch prolongs battery life by allowing display only when actually probing . The CP Gun is rated to depths of up to 300 m (~1000 ft). The Polatrak Cathodic Protection CP Gun is designed for situations where a few contact CP readings are required. Like all Polatrak probes, it has twin elements and dual readouts which provide an unparalleled level of accuracy and redundancy.
The CP Gun kit comes complete with operating and calibration instructions and a comprehensive supply of spare parts.
Key Design Points
TWIN ELECTRODES
Replaceable, dual silver / silver chloride (Ag/AgCl) electrodes provide real-time calibration and allow the dive to be completed even if an electrode fails.
BATTERY LIFE
The Polatrak Cathodic Protection CP Gun uses two standard 9V batteries, which are easily replaced in the field. With its convenient on/off switch, the batteries can last the entire dive season.
SERVICEABLE
The sturdy design of the Polatrak CP Gun probe allows easy replacement of worn or damaged parts without having to replace the entire probe. It can be serviced easily in the field.
BRIGHT LED’s
The CP Gun has bright, backlit LED readouts that help the diver see CP readings in low-visibility conditions.
