APPLICATION AREAS
The Leeb Probe Type D is ideal for general-purpose hardness testing, capable of handling a broad spectrum of materials and conditions. Its moderate impact energy of 11 Nmm and robust design make it a go-to choice for most testing scenarios where precision and durability are required.


ADAPTABLE TO VARIOUS TESTING CONDITIONS
The Leeb Probe Type D can be used with samples of different weights and thicknesses:
- Minimum sample weight:
- Of compact shape: 5 kg (11 lbs).
- On solid support: 2 kg (4.5 lbs).
- Coupled on plate: 0.05 kg (0.2 lbs).
- Minimum sample thickness:
- Uncoupled: 25 mm (0.98 inch).
- Coupled: 3 mm (0.12 inch).
- Surface layer thickness: 0.8 mm (0.03 inch).
VERSATILE AND ROBUST
The probe’s tungsten carbide tip, with a diameter of 3 mm and a hardness of 1600 HV, ensures durability and precision. It is designed to measure hardness up to 940 HV, making it versatile for a variety of materials from softer metals to harder alloys. The moderate indentation size and depth help maintain surface integrity while providing accurate results.


MODERATE INDENTATION FOR GENERAL TESTING
The probe produces moderate indentation sizes on test surfaces, making it suitable for general-purpose hardness testing:
- Indentation size on test surface:
- With 300 HV, 30 HRC: 0.54 mm diameter, 24 μm depth.
- With 600 HV, 55 HRC: 0.45 mm diameter, 17 μm depth.
- With 800 HV, 63 HRC: 0.35 mm diameter, 10 μm depth.
