MARTINDALE CD1000 Cable Detector Kit

The Martindale CD1000 Cable detector kit is ideal for tracing cables in walls and underground, locating fuses/breakers on live or dead circuits. It assists electrical engineers locating interruptions and open-circuits in cables and electrical floor heating systems. It can be used for tracing metallic water and heating pipes.

Using advanced digital circuit technology the Transmitter sends, to the target cable, an AC voltage modulated by digital signals which generate an alternating electric field. The alternating field is detected by the receivers head, magnified and decoded. By localising the maximum signal strength detected, the path of a cable can be traced, a fuse can be found or a break in a cable/conductor can be detected.

The CD1000 is supplied as a complete kit: 1 x Transmitter and 1 x Receiver in a case, set of test leads with crocodile clips, earthing rod, batteries and instructions.
