Hardness tester combines our best selling Rockwell hardness tester with our new digital indicator upgrade. This brilliant combination gives you the very best functions of a digital Rockwell hardness tester yet has the ease of use of our analog hardness testers. Conforming to ASTM E-18 Rockwell Hardness tester standards, A perfect, rugged performer suited for any environment including heat treat facilities, tool rooms, workshops, laboratories and inspection labs.
The Rockwell hardness is determined by the application of a preliminary test force (minor load or preload), followed by an additional load (major load) to reach the total required test load. The minor load provides the zero or reference position. The major load is applied and held for a predetermined amount of time (dwell time) to allow for elastic recovery. Then the major load is removed, while still maintaining the minor load.
