LCD Auto Lifting Rockwell Hardness Testing Machine Material
Hardness Testing Equipment
Motor driving lifting mechanism make the testing more easily. Just
press “START” key once, whole process will be finished
automatically. No matter the size of the sample, the position of
the sample, the distance between the indenter and sample surface.
The sample will be auto-lifted to approach the indenter and
finishing testing automatically.
Better testing accuracy than handle wheel lifting type which
effected by human factors.
Integrated casting body with more wide iron basement leads to more
Twin tester--Regular Rockwell & Rockwell Superficial hardness
for metal and plastic material.
Horizontal Protrudent Indenter Design, suitable for internal and
Testing on Surfaces difficult to reach by normal design. Easy to
test 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.
The tester is suitable for testing of carbon steel, alloy steel,
cast iron, non ferrous metal.
Measuring results displays on LCD directly and can be printed, or
transmitted to external computer automatically by USB or RS-232
data output port.
Test value can be converted to the value of HB, HV, HK and σb
Curved surface correcting automatically.
The tester conform following standards 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.
The diamond penetrator is used for testing materials such as
hardened steels and cemented carbides. The carbide ball
penetrators, available with 1/16 inch, 1/8 inch, 1/4 inch, and 1/2
inch diameter, are used when testing materials such as steel-copper
alloys, aluminum and plastics to name a few.
Rockwell testing falls into two categories: Regular Rockwell
testing (e.g., C and B scales) and Rockwell superficial testing
(e.g., 30 N and 30 T scales).
High Rockwell hardness numbers represent hard materials and low
numbers soft materials.
