The SH-21 is designed for precise measurement of hardness in difficult-to-reach areas of compact parts, metal casts, gears, crankshafts, component parts, and more. It is ideal for the inspection and maintenance of large-scale structures, vehicles, ships, steel towers, bridges, and aircraft.
- Fast action, measures hardness in seconds.
- Practically undetectable measurement technique leaves indentations of 0.1mm2 allowing use on finished products.
- Displays hardness in HV (Vickers), HRC (Rockwell), HS (Shore) and HB (Brinnel) units.
- Measurement can be converted to tensile strength, N/mm2
- Readings not affected by surface underneath test sample.
- 2000 Reading data memory can be transferred to PC.
Supplied as a complete kit including display, probe, hardness test block (approx 55HRC), 1.5m probe cable, 100-240V AC Adapter, Battery charger, 1 Li-On battery, carrying case.
