· HR450 can be used directly to
measure Rockwell Superficial hardness for metal and plastic
material.
· Provided with many features
such as high measuring precision, wide measuring range with 15
Rockwell scales.
· Automatic test force switch
according the selected scale without manual operation.
· Automatic load cycle. The
loading, dwell, unloading process of the main test force are
controlled exactly to meet standard.
· Measuring results digitally
displaying and can be printed, or transmitted to external computer
automatically.
· The tester is suitable for
testing of carbon steel, alloy steel, cast iron, non ferrous metal,
and engineering plastic etc., especially small and thin parts.
· Test value can be transformed
to the value of HB, HV, HK and σb value.
· The tester meets all the
following standards such as ISO 6508-2, ASTM E18, BS EN ISO6508-2,
GB/T230.2.
