Duct Sonde 33kHz

  • The C.Scope 33KHz Duct Sonde is a small battery powered transmitter which, in typical use, would be screwed onto the end of a duct rod and pushed down a duct so that the direction can be traced using a C.Scope locator set to 'Signal Generator Mode/Transmitter Mode'.
  • The location of a blockage can be identified using this system, with enormous cost saving potential.
  • Very robust waterproof plastic construction.
  • 'O' ring battery compartment seal.
  • Stainless steel end fittings.
  • Battery low indicated by continuous 32768Hz signal.
  • Compatible with most rods.
  • Resin sealed electronics.
  • Simple to use.
