Application

For the majority of your hardness testing requirements.

Use in very confined spaces, e.g. in holes, cylinders or for internal measure‐ ments on assembled machines.

For measurements in extremely confined spaces or at the base of grooves.

For measurements in grooves or recessed surface.

Surface hardened components, coatings, thin walled or impact sensitive components (small measuring indentation).

Solid components. E.g. heavy castings and forgings.
