Description

Dynamic Lead Probe for Hardness Tester

The Leeb Probe method is as follows: impact body with a certain weight hits the testing object. The sensor detects the speed of the impact body before and after the impact. Hardness according to Leeb determined by the ratio of rebound velocity (V1) and impact velocity (V0). The instrument converts the ratio of speeds to hardness value in accordance with formula

Main advantage of the Dynamic Leeb probe is the possibility of hardness testing of:

– coarse grain materials;

– surface with a high roughness;

– high-alloy steels and non-ferrous metals;

– forged products.

1. 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.
