Three new models for micro hardness testing

Zwick has introduced three models of the ZHVμ micro hardness instrument, providing users with high accuracy and varying levels of automation depending on the application and budget.

The ZHVμ us available in manual, semi-automatic and fully automatic configuration, each tailored to individual customer requirements.

A test force range of 10-2,000gf and the ability to supply four objective lenses and two indenters (Vickers and Knoop) in a motorized turret ensures total flexibility in defining the specification of the instrument.

The ZHVμ -A version provides fully automatic operation, therefore eliminating the operator influence from all aspects of the test and measurement process. This reduces measurement uncertainty and ensures consistent results between different operators. The ability to scan the entire surface of the sample in order to quickly and accurately position multiple test points is said to be a major benefit over the traditional manual method. This functionality makes the ZHVμ -A ideal for effective case depth determinations of hardened layers and heat-affected zone investigations of weld sample sections.

The ZHVμ is supplied with UKAS calibration certificates to ISO 6507, ISO 4545 and ASTM E384 standards and is therefore compliant with Nadcap and ISO 17025 quality assurance standards. This ensures that the ZHVμ is verified for use in all industry segments.
