Impact Devices For Hardness Tester


Impact device D: Universal device for most hardness requirements


Impact device DC: Ultra-short version; manually loaded on the front; same characteristics as type D; for testing in boreholes,built-in parts, hollow cylindrical parts, etc.; max. 940 HV


Impact device DL: With extremely long and fine front piece only for steel and cast steel; for testing in narrow or hard to reach areas; max. 950 HV


Impact device D+15: The front part is narrow and the coil is located behind it; same characteristics as type D; only for steel;for hardness testing in slots, grooves, recessed areas, gear flanks,grooves, cavities, tooth flanks, etc.; max. 940 HV


Impact device C: Reduced impact energy of about 1/4 of type D; for tempered or surface treated steel, small or sensitive-to-shock parts (minimal imprint is left); max. 1000 HV


Impact device G: With large test-tip diameter; impact energy 9 times larger than type D; on steel, gray or nodular cast iron; for large cast parts and forgings or parts with high surface roughness;max. 650 HB (only in Brinell)


Impact device E: With a synthetic diamond test tip of approx.5000 HV; for very hard materials (above 50 HRC / 650 HV) such as carbide, barrels, etc.; max. 1200 HV
