C.Scope 33 kHz Duct Sonde


BRAND: C.Scope

Price ex VAT

The C.Scope 33KHz Duct Sonde is a small battery powered transmitter which can be screwed onto the end of a duct rod and inserted and fed into a a duct or conduit. The direction of the duct or conduit can then be traced by a C.Scope locator set to Generator/ Transmitter Mode. The location of a blockage can be identified using this system with enormous cost saving potential.

Often the standard sized Sonde is too large to pass between cables when tracing electrical, telecommunication or cable conduits or ducts.

The solution is the C.Scope 33kHz Duct Sonde. The small diameter Duct Sonde, developed in conjunction with British Telecom, can be fed easily inside ducting without snagging.
