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. |
