SHR-3100 Digital Rockwell Superficial Hardness Tester

◆Horizontal protrudent Indenter Design, suitable also for internal and external testing.
◆Testing on Surfaces difficult to reach. Testing internal surface of rings and tubes with diameters over 33mm. (Min dia.15mm using a goose neck)
◆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 superficial scales.
◆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.
◆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 by USB or RS-232 data output port.
◆Test value can be transformed to the value of HB, HV, HLD, HK and value.
◆The tester meeting the following standards such as GB/T230.2, ISO 6508-2, ASTM E18 and BS EN ISO6508-2.
