      Standard Search Head

      Designed to meet most of your measurement requirements.

      Narrow Pitch Search Head

      Accurately measures the cover thickness when the gaps (pitch) between each of the rebars are close together.

      Deep Cover Search Head

      The ideal search head for accurately measuring rebars that are deep within the structure.

      Dual Search Head for high tensile and stainless steels

      The search head is designed to locate High Tensile and Stainless Steel.

      Borehole Probe

      The solution for locating tendon ducts and multiple layers of rebar lying deep within the concrete. 

      Half-Cell Kit

      Consists of either a copper electrode in a copper sulphate solution or a silver electrode in a sodium chloride solution, each half cell is a sealed unit - no need to mix chemicals. Supplied with a 25m / 80' cable, every half-cell probe is guaranteed for 5 years.

      Extension Cable 100m / 325ft

      The extension cable for use with the half-cell kits gives the flexibility to take readings in difficult to reach areas.

      Verification Block

      The verification block allows the user to check the calibration of their gauge in order to ensure maximum measurement accuracy.

      Extension Arm Kit

      This kit allows the user to scan bridge decks and floor areas using the hand-held search heads from a standing position as both the standard or narrow pitch search head can be attached to the extension arm.
