Probe E is a replaceable probe for Leeb Hardness tester TQ-3C.
Probe with indenter made of polycrystalline of boron nitride intended for control of materials with high hardness.
The Probe E is used for hardness testing:
- All basic types of metals and alloys without additional calibrations (structural, tool, corrosion-proof, heat-proof, non-corrosive steels and alloys as well as alloys of nonferrous metals, castiron, aluminium, bronze, brass).
- Items with surface hardening and high frequency current hardening.
- Items of complicated configuration.
- Heavy and big items with rough surface.
Advantages of Leeb probe
- Hardness measurement in hard-to-reach areas.
- The spatial position of the probe does not affect the measurement result.
- The robust housing is not subject to mechanical stress.
- Long service life.
