Bowers W-INMR/01 portable hardness tester has a magnetic quality

A portable magnetic Rockwell hardness tester, designated the W-INMR/01, has been introduced by Bowers Metrology to enable large components to be tested in situ rather than transported to static devices.

Bowers' W-INMR/01 has an accuracy specification that complies with ISO 6508 or ASTM E18. It features a test head that can be fixed to the surface of iron and steel components by a strong magnetic force. When applied, the instrument's 350 kg-plus magnetic base holds the unit firmly in position without having to support the test piece. The portable hardness tester is suitable for large assemblies or workpieces that it is inconvenient to move – like moulds, steel plates, steel tubes, steel structures, boilers, pressure vessels, metallic pipe lines or machine tool elements such as slideways. The W-INMR/01's 4.9 kg net weight and convenient aluminium carrying case make it ideal for both workshop and field use. Hardness testing procedures can be performed regardless of the shape of the component under inspection provided that there is a flat surface for positioning the magnetic base, or in the case of cylindrical parts, the units removable V supports can be used. The tester has an initial test force of 10 kg with Rockwell test forces of 60, 100 or 150 kg applied via a 120° diamond cone indenter or a 1.588 mm carbide ball. Fifteen hardness scales are available including Rockwell hardness HRC, HRB and HRA.
