Encode anything. The ODI is perfect for limited access applications.

The ODI features an encoder attached to a straightforward, universal clamp system, allowing virtually any combination of probe and wedge to be held. The small size allows for single-handed operation in confined spaces, and the clamping system means probe setup is quick and easy.

Part ID: CKG009



Quick Adjust Clamp

Affix any probe/wedge to the ODI with ease (no tools required).

Condensed Scan Size

Useful during limited access inspection as the small stature allows for unique scanning opportunities.


The attached mini encoder provides precise encoded positional information while being compatible with all standard instruments.

Alternate Encoder Position

Position the encoder at 0° or 90° to accommodate different clamping arrangements. The spring-loaded wheel ensures positive contact with the inspection surface.

Additional Stainless Steel Wheel

Each ODI kit also includes a heat treated SST encoder wheel which can prove useful when using gel couplants.


A three-year limited warranty is included with all products.
