Key features of our absolute pencil probes

  • Equally applicable to the high frequency surface inspection of ferromagnetic and non-ferrous material.

  • Double shielded for use close to materials edges and vertical metal faces (mass effect) with both an outer stainless and an inner ferrite shielding.

  • Featuring a plastic handle made from delrin with neoprene rubber rings and finger scallops for comfortable and stress free handling leading to a more reliable and accurate inspections.

  • Dis-connectable using a microdot connector for rapid changeover.

  • Locking 4 way lemo connector available with inbal probes.

  • Inbal probes feature an internal balance load and thus simplify setup and offer the ultimate in signal to noise ratio permitting smaller defect to be detected.

  • Standard probe frequencies available with a wide range of operating frequency 200khz (50-600khz), 500khz (150k-1.5mhz), 2mhz (650k-6mhz) and 6mhz (2-18mhz) meaning one probe may be used for a wider range of applications.

  • Each frequency (except 6mhz) available in standard and fine tip size.

  • Probes offered as standard with fixed dimensions but can be supplied in many other configurations.

Absolute unshielded broad band probes - for general-purpose inspection of surface breaking defects and metallurgy / conductivity variations and to estimate coating (paint) thickness.


Key features

Key features and particular specifications that apply to the broad band probes include:


  • Broad range with centre frequency  – 5khz, 20khz, 100khz, 500khz, 2mhz

  • Plastic handle with neoprene grip

  • Bnc connector


Rotating Probes (Reflection) are available in two options, Rigid Stainless Steel and Delrin Flexible. Rigid stainless steel probes offer high wear resistance, where as the flexible probes are used where hole tolerances are poor and access is not directly in-line with the hole.


ETher NDE can offer a broad range of Eddy Current (ECT) Weld Probes including specially designed Eddy Current (EC) Weld Probes to your specification.

Eddy Current Weld Probes are specifically designed for the task of weld inspection of non-ferrous welds and steel structures. They can detect surface cracks on a weld with a non-conductive surface coating on it of up to 2mm.

The application specific design of the probe means that it is capable of inspecting welds with uneven surfaces and coatings on them.

Welds are often coated or painted making access to the weld for inspection more complicated when using other methods to Eddy Current (EC). For example, MPI and Dye Penetrant Inspection require the removal of the coating before inspection, costing both money and time. Eddy current (ECT) Weld Probes allow welds to be efficiently inspected for near-surface cracks because the weld can be inspected through paint or metallic coatings.


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 general purpose inspection of sub-surface corrosion and flaws.

This probe has excellent depth penetration making it ideal for multi-layer inspections with a broad frequency ranges, excellent low frequency performance, integrated 4-way Lemo connector and built in balance coils


Typically used on aircraft wings (and on other similar structures) to detect cracks and corrosion on or near the surface around fasteners and in deeper layers under the skins.

The above probes either slide along or over rows of fasteners
