Leeb Rebound Hardness Testing Device

The “HARDMATIC” HH–411 is a light-weight portable hardness testing instrument for metal workpieces. It works on the rebound hardness principle (standardized according to ASTM A 956). Measurement is conducted with hardness value L (Leeb-value), however, conversion to any desired hardness scale can be performed.In addition the display automatically shows OK/NG with the tolerance function set and selected.Memory function for 1800 measured values.Automatic measuring direction angle-compensation of the given angle.
