The various hardness testers in the Rockwell product group perform classical Rockwell methods (load: 60 - 150 kg), superficial Rockwell methods (load: 15 - 45 kg) and combinations of Rockwell and superficial Rockwell methods (load: 15 - 150 kg).
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.
