ETher ID Probes

ETher ID Probes


Our range of ID Probes are designed hand in hand with our Cables to offer the best options when working in the field. With our Dis-connectable Cables, if either the Probe or Cable fails, the operator can easily swap them for another and carry on with their inspection reducing interruption to their inspection and the cost of having to replace both the Probe and Cable. 


  • For internal diameter tube inspection of non-ferrous tubular heat exchangers, condensers, air conditioning.


Rigid Push / Pull Dis-connectable Cable

Flexible Dis-connectable Cable


  • Robust and reliable design with Stainless Steel End Caps to give longer life span.
  • Probe diameters from 7.5 to 150mm, available in 0.1mm steps
  • Choice of cable options; PVC Push/ Pull (Rigid), Polyurethane (Semi-Rigid) or Flexible Dis-connectable and integral probe cables
  • Cable lengths from 3.0 to 30m
  • Wide variety of instrument connectors supported
  • Choice of probe frequencies to ensure best results
  • Frequency Range from 1.4kHz to 1.5MHz, center frequencies 2.7, 10, 24, 76, 190, 400kHz
  • Cross axis and driver / pickup options are available upon request.


When ordering ID probes allow 0.8 to 1.5mm less than the tube diameter, this should be good for typical tube condition and manufacturing tolerances. Where tolerances are poor allow for greater clearance, tape can be used were necessary to reduce probe ‘wobble’.
