Applications

The hardness testers in the ZHR product group cover the following methods.

  • Classical Rockwell methods (ZHR4150)
    as per ISO 6508 and ASTM E18.
    pre-load: 10 kg. test load: 60, 100, 150 kg
    scales: A B C D E F G H K L M P R S V.
  • Superficial Rockwell (ZHR4045)
    as per ISO 6508 and ASTM E18
    pre-load: 3 kg. test load: 15, 30, 45 kg
    scales: N T W X Y.
  • Universal Rockwell (ZHR8150)
    as per ISO 6508 and ASTM E18.
    pre-load: 3, 10 kg. test load: 15, 30, 45, 60, 100, 150 kg.
    scales: A B C D E F G H K L M N P R S T V W X Y.
  • Rockwell for plastics (LKP)
    as per ISO 2039-2 and ASTM D785 (A & B).

Advantages

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

Automated Rockwell test

Automated testing system for Rockwell and superficial Rockwell test methods to EN ISO 6508 and ASTM E18, incorporating an automated sample feeding system for testing up to 36 samples. Shape and size of samples can vary to suit customer specific requirements.
