• D-probe: A universal standard unit that can handle most hardness testing applications
• D+15-probe: Has a very narrow contact area and a set back measurement coil
• DC type impact device: A built-in DC impact body
• C: Can test small, light, thin parts and the surface of a hardened layer
• G: Can test large, thick, heavy, and rough surface steel

Impact device G has far greater impact energy than the standard impact device D – roughly 9 times as much. Typical applications are Brinell-range heavy coarse grained castings and forgings, especially of steel and cast steel, cast iron (lamellar and nodular graphite), and cast aluminum. In comparison to impact device D, impact device G requires less surface finish, but leaves a larger indentation. Maximum hardness: 646 HB including device, Impact Body G, and Support Ring

• E: Can test super high hardness material
