Twin tester--Regular Rockwell & Rockwell Superficial hardness for metal and plastic material.

Horizontal Protrudent Indenter Design, also suitable for internal and external testing.

Testing on surfaces difficult to reach. Testing internal surface of rings and tubes with diameters over 23mm.

Testing force is set automatically according to testing scale

Provided with many features such as high measuring precision, wide measuring range with 30 Rockwell scales.

Measuring results digitally displaying and can be printed, or transmitted to external computer automatically by USB or RS-232 data output port.

Test value can be transformed to the value of HB, HV, HK and σ B value.

The tester meeting all the following standard such as ISO 6508-2, ASTM E18.

The Rockwell test consists of measuring the additional depth to which a carbide ball or diamond penetrator is forced by a heavy (major) load beyond the depth of a previously applied light (minor) load (SET point).

The minor load is applied first and a SET position is established on the dial gauge or displacement sensor of the Rockwell tester. Then the major load is applied. Without moving the piece being tested, the major load is removed and, with the minor load still applied, the Rockwell hardness number is automatically indicated on the dial gauge or digital display.

SHR-145N Series Application:

Rockwell B Scale HRB: Copper alloys, soft steels, aluminum alloys, malleable iron, etc.

Rockwell C Scale HRC: Steel, hard cast irons, pearlitic malleable iron, titanium, deep case hardened steel, and other materials harder than B100.

Rockwell A Scale HRA: Cemented carbides, thin steel, and shallow case-hardened steel.
