Rockwell Superficial Hardness Tester HR450
|
Detailed Product Description
|
· 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. · Preload:29.4N(3kgf) · Total test
