Product Description
D+15 Probe Leeb Hardness Tester for Groove and Reentrant Surface Testing
Product Overview
The D+15 probe is specifically designed for Leeb hardness testing on grooves, recessed surfaces, and hard-to-reach areas where standard probes cannot access. With its thin front section and withdrawn measuring spool, this impact device provides accurate hardness measurements in confined spaces.
Key Features
- D+15 type impact device with 20mm diameter and 162mm length
- 11mJ impacting energy with 7.8g mass impact body
- 3mm tungsten carbide test tip with 1600HV hardness
- Maximum sample hardness capability: 940HV
- Minimum sample thickness: 5mm
- Surface roughness requirement: 1.6μm Ra
Compatible Materials
Steel and cast steel, metallurgical tool steel, forged steel, gray cast iron, ductile cast iron, cast aluminum alloy, pure copper, copper-zinc alloy (brass), and copper-tin alloy (bronze).
