Overview

HBRV-187.5 Blowe Three purpose Hardness Tester

Product Details

HBRV-187.5Type Blowe Three purpose Electric Dial Hardness TesterIt has multiple testing forces and multiple indenters, used to determine the Brinell, Rockwell, and Vickers hardness of metal materials. Suitable for hardness measurement of ferrous metals (steel, cast iron, soft steel, quenched steel, etc.) and non-ferrous metals (aluminum alloys, copper alloys, etc.), and can also measure the hardness of hard alloys, carburizing layers, and chemical treatment layers. This machine adopts a rotating test force transformation mechanism and an optical measurement system. It is equipped with a microscope measuring device on the body, which is easy to use, reliable in load variation, and stable in indication. It can be widely used in industries and places such as metrology, mechanical manufacturing, metallurgy, building materials, scientific research and production.
