Universal hardness tester

NEXUS 7700

General information

The traditional swivel system (indenter/objective) universal hardness tester previously equipped with a matt screen, nowadays has a modern video indent measuring system with 18 Megapixels camera, an ultra-fast Windows i7 controller, automatic measurement and can be used for all hardness procedures; Brinell, Vickers, Knoop, HVT and HBT according to DIN, ISO standards.

The NEXUS 7700 also covers all Rockwell and Superficial Rockwell hardness scales. In combination with a manual or motorized CNC XY-stage the tester offers the option of running case depth hardness programs, pre-defined testing patterns and/or other specific or special tasks defined by the user.

Perfectly suitable for testing hardness of castings and forgings, wide application within the automotive and aerospace industry or laboratory and workshop testing.
