The different devices of the Rockwell family are designed for the classical Rockwell methods, the Super-Rockwell methods, and for combinations of these methods.
Zwick/ZHR - Rockwell Hardness Testers
The Rockwell Zwick/ZHR hardness testers cover the following applications:
- Classical Rockwell methods: Zwick/ZHR 4150 (preload: 10 kg; test load: 60; 100; 150 kg), scales A B C D E F G H K L M P R S V.
- Super-Rockwell methods: Zwick/ZHR 4045 (preload: 3 kg; test load: 15, 30, 45 kg), scales N T W X Y.
- Combinations of Rockwell and Super-Rockwell methods: Zwick/ZHR 8150 (preload: 3, 10 kg; test load: 15, 30, 45, 60, 100, 150 kg), scales A B C D E F G H K L M P R S V N T W X Y.
Furthermore the devices are available in different degrees of operator convenience:
- Models with one button operation for simple test tasks (types AK, Typ BK).
- Models with line display and integrated conversion functions for standard applications (type LK).
- Models with touchscreen, expanded functions and high operational comfort for comprehensive test tasks. They are employed for testing batches (type SK), and for production control (type TK).
The modular system of these hardness testers with its range of accessories enables the Rockwell hardness testers to be harmonized with the application at hand.
The Rockwell hardness testers are characterized by an indentor mounting for hardness tests at measurement locations that are difficult to access and ensure ease of operation.
Features:
- Automatic test cycle
- Automatic load application and load removal
- Automatic data analysis including evaluation
- Selection of the loading weight via a rotary knob or via a touchscreen (automatic load change)
- Robust construction with play-free, ball lead screws
- Test area up to 292 mm in height for tests on large components
- Input of tolerance parameters
- RS 232 interface as standard
- A range of standard accessories; indentor, support table, hardness comparison plates
The test results can be sent direct to a printer via the RS 232 interface or can be linked and then further processed and archived in testXpert® via the test program.
