TQ-3C Special – Rebound (Leeb) hardness tester
Leeb hardness testers
High-precision hand-held instrument engineered for demanding production and field conditions, delivering reliable non-destructive testing capabilities. Designed for assessing production quality, it finds utility across various industries such as metallurgy, mechanical engineering, aircraft, shipbuilding, atomic industry, and oil and gas.
Operating on the Leeb method, this hardness tester provides robust control over the hardness of a wide range of materials, including:
- All basic types of metals and alloys without necessitating additional calibrations (such as structural, tool, corrosion-proof, heat-proof, non-corrosive steels and alloys, as well as alloys of nonferrous metals, cast iron, aluminum, bronze, and brass).
- Components with surface hardening and high-frequency current hardening.
- Complex-shaped items.
- Heavy and large items with rough surfaces.
Operational advantages
- Wide range of controlled metals and alloys.
- Low sensitivity to surface curvature and roughness.
- Monitoring of hardness changes along the surface.
- Stable measurements independent of force and time of probe pressing.
- Material identification capability in blank production.
- Control of “volumetric” hardness.
Features
- Impact-, dust-, and water-proof housing.
- Bright color display for operation in sub-zero temperatures, remaining visible under varying lighting conditions.
- Signalization of threshold readings exceedance.
- Unique system for statistical data processing and averaging of readings.
- Swift adjustment of readings and programming of additional calibrations to basic scales using two or fewer standard blocks.
- Flexible device memory for recording and analyzing readings.
- Programming of additional scales calibrations by two or fewer standard test blocks.
- Rapid programming of additional scales using two to ten standard test blocks.
