Innovative technology for effective measurement operations

The device’s 3D-antenna system enables both inductive and passive localisation of pipes and cables from any position and direction, independent of the user’s location.

Simple to operate, simple to learn.

You can check at any time whether or not you are still located over the target line by means of the continual display of depth and current and the selectable acoustic ­distance signal.

The search result can be reliably verified via the easily understandable cartographic display which shows direction arrows, signal strength and proximity signal.

With the SR-20, you can carry out the most difficult localisations and mark supply lines reliably; even branch lines from other directions – and even lines whose existence was previously completely unknown to you!

Standard equipment SR-20:

SR-20 detector, markers and mast holders, batteries, operating manual

Optional equipment:

Additional probe markers, ST-33Q trans­mitter, ST-510 trans­mitter, ST-305 transmitter, induction clamp, separate transmitter, floating transmitter
