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.
