Overview
The TJ-HP180 is a portable Leeb rebound hardness tester using the standard 18.7 J D-probe. It is widely used for quick hardness inspection and sorting of castings, welds, rolls, bearing steels and large in-service structures.
Being non-destructive and portable, it suits field sorting, acceptance and re-inspection of large batches, delivering HLD readings in seconds with automatic conversion to HB, HV and HR.
Typical uses
- Batch hardness sorting of castings and forgings
- Field acceptance and re-inspection of vessels, pipes and bridges
- Surface hardness and effective case depth assessment
- Cost and time saving versus laboratory hardness testing

FAQ
Can a Leeb tester replace laboratory hardness testing?+
Leeb hardness is a dynamic, non-destructive approximation. Conversion to static Brinell/Rockwell/Vickers values carries an empirical relationship, typically within ±5%. It is well suited to field sorting and acceptance, but contractual judgement or failure analysis should still rely on laboratory methods.
Does the workpiece need machining?+
No. Leeb testing tolerates rough surfaces — just remove paint, oxide scale and burrs so the impact point is flat. No dedicated test specimen is required.
