Product Overview

SHRS-450 Series Surface Rockwell Hardness Tester

Brief Introductions:
SHRS-450M is an effective and affordable superficial Rockwell testing machine with high accuracy, reliability and durability, it is applied in the workshops and measurement departments for determining the Rockwell hardness of ferrous and non-ferrous metals.
SHRS-450E adopts the design of load test force in electric, load force 15, 30, 45Kg is selected by dial knob, test force is loaded in switch control, and tested result: HRA, HRB, HRC is showed on the analogue gauge.
SHRS-450D adopts the design of load test force in electric, except to lift up the anvil and chose the test force, other operations are entirely automatic, and the test force, dwell time, load and unload process, and test results are displayed on LCD screen, which avoid the man-made error and enhance the measuring accuracy, meanwhile, built-in mini-printer can record and print the main measuring data for reducing human working intension.
