Rockwell Hardness Testing Instrument - Zwick ZHR

Unique Accessibility

The various hardness testers in the Rockwell product group are used for classical Rockwell methods (load 60 - 150 kg), Rockwell/superficial Rockwell combinations (load 15 - 150 kg) and superficial Rockwell methods (load 15 - 45 kg).

Key Advantages and Features

  • Comprehensive equipment included in delivery
  • RS232C interface as standard
  • Nose-mounted indenter allows testing at difficult-to-access measurement points
  • Separate indenter, for extended range of application
  • Completely automatic test sequence (including automatic evaluation) prevents operator influence on test results
  • High test-result reproducibility
  • Audible and visual signals when specified tolerances exceeded and during pre-load setting
  • Special specimen holders/grips to suit individual customer requirements
  • Rugged construction with zero-backlash, ball-bearing-mounted lead-screw
  • Test-area height up to 250 mm allows testing of larger workpieces
