Features:
*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.
* Upper/lower limits setting & alarming
*Curved surface correcting automatically
*The tester meets all the following standards such as ISO 6508-2, ASTM E18, BS EN ISO6508-2, GB/T230.2.
