Product Description
Checkline SH-21 Metal Hardness Tester - Rockwell HRC
Displays hardness in HV (Vickers), HRC (Rockwell), HS (Shore) and HB (Brinnel) units.

The Checkline SH-21 (now SH-21A) is designed for precise measurement of hardness in difficult to reach areas of compact parts, metal casts, gears, crank shafts, component parts and more. It is ideal for inspection and maintenance of large-scale structures, vehicles, ships, steel towers, bridges, aircraft.
