Hardness Tester uses LEEB rebound principle.
Press Release Summary:
Handheld HardChecker meets ASTM Standard A956-00. It has two-key operation, digital read-out on large LCD, and conversion tables for 9 materials: steel, tool steel, stainless steel, gray cast iron, nodular iron, aluminum, brass, bronze, and copper alloys. It uses 3 mm dia tungsten-carbide ball for impact indenter. Hardness measurement is independent of test direction. It comes with 2 AAA batteries, suitable for 4000 measurements.
