DIGITAL ROCKWELL HARDNESS TESTERS
MAKE DINESH SCIENTIFIC
DESCRIPTION
A precision tool used to determine the hardness of materials is a digital Rockwell hardness tester. To ascertain the hardness of metals, alloys, and other materials, the Rockwell hardness test is frequently used in production, quality assurance, and research. A digital Rockwell hardness tester the following important features:
DIGITAL DISPLAY:
- Digital Rockwell hardness testers have electronic displays instead of analog indications, which allows them to provide accurate and readable hardness results.
MICROPROCESSOR CONTROL:
- Microprocessor-based control systems are frequently incorporated into these devices, enabling precise and consistent test results. The testing procedure automated more effectively using digital control.
AUTOMATIC LOAD APPLICATION:
- Automatic test force loading and unloading is a common feature of digital Rockwell hardness testers, which lowers the possibility of user error and guarantees consistent test conditions.
SELECTABLE SCALES:
- Depending on the material being tested, they may support a range of Rockwell scales (e.g., HRC, HRB, and HRA).
- The flexibility to move between scales makes it possible to test various materials with various degrees of hardness.
DEPTH MEASUREMENT AND INDICATION:
- A built-in depth-measuring mechanism in many digital Rockwell hardness testers precisely detects the depth of the indentation, which enhances the accuracy of hardness readings.
DATA RECORDING AND ANALYSIS:
- Certain models have data logging features that let users save and examine the results of hardness tests. Documentation and quality control are aided by this capability.
FEATURES:
SAFETY INTERLOCKS:
- Mechanisms called interlocks stop a machine from working if specific requirements aren’t fulfilled. For example, the machine might not start if the protective cover is not closed properly, or the test chamber might be made so that it cannot open while the test is running.
