Leeb hardness tester M502.231 — portable Leeb D rebound tester with OLED display

The Leeb hardness tester M502.231 is a portable rebound hardness instrument designed for quick, repeatable hardness checks on castings, forgings and finished components across common engineering alloys.

• Wide measurement range HLD / HRC / HV / HB
• OLED display, readable in sunlight
• Stores up to 300 readings
• Rechargeable lithium battery with 10 h runtime

Robust portability for fast, shop‑floor decisions

The compact rebound tester offers a combination of portable design and industrial robustness that supports rapid quality checks directly at the production line or in maintenance rounds. With a total weight of 2 kg and a user‑friendly probe, the instrument enables swift positioning on components while maintaining a ±0.5% accuracy rating and a repeatability of 0.8. The OLED display presents results in multiple hardness scales and remains legible under strong ambient light, so operators can record measurements confidently even outdoors or in brightly lit shops. Overall, the form factor reduces handling time and contributes to faster decision cycles in production and inspection processes.

Measurement scope and material coverage for diverse applications

Using the Leeb D method, the device covers a broad measurement range (170–960 HLD, 17–68.5 HRC, 80–976 HV, 19–651 HB, 30–100 HS, 59–85 HRA, 13–100 HRB), making it suitable for steels, stainless steels, cast irons, aluminium alloys, copper and brass as well as numerous non‑ferrous alloys. This range supports routine acceptance testing, incoming goods inspection and verification of heat treatment outcomes. The rebound principle converts impact energy into hardness values that are displayed in the selected scale, providing immediate, comparable results without complex calculation steps; this simplifies integration into existing quality workflows and reduces the need for multiple specialised instruments.

Practical data handling and accessories for traceable records

Built‑in memory stores up to 300 readings, enabling batch recording and later transfer for documentation. The unit runs on a rechargeable lithium battery with around 10 hours of continuous operation and a 200‑hour standby time, reducing downtime and the need for frequent battery changes. Supplied accessories include a support ring for small, round workpieces, charging cable, power supply and a cleaning brush, all housed in a transport case for safe storage and mobility. Together, these features facilitate reproducible measurements and straightforward on‑site record keeping, supporting traceability and process control in production environments.
