Versatile Hardness Testing CapabilityThis tester is engineered to deliver reliable hardness measurement for a wide array of materials such as metals, alloys, ceramics, and surface-treated specimens. Its flexible load range and adjustable dwell time allow users to tailor test conditions precisely, making it suitable for both research and quality control environments.
Accurate Optical MeasurementThe integrated microscope offers up to 400X magnification with a scale resolution of 0.1 micron, ensuring detailed and repeatable measurements. The optical display, alongside optional digital readout, enables clear visualization and documentation of indentation sizes, supporting thorough analysis in accordance with international standards.
FAQ's of Vickers Hardness Tester:
Q: How does the Vickers Hardness Tester operate?
A: The tester employs a Vickers diamond pyramid indenter to create an impression on the test material under a specific load (5 kgf to 50 kgf). Users set the desired dwell time (5 to 60 seconds) and observe the indentation using the optical microscope to measure hardness values (10 HV to 1000 HV), either via an optical scale or an optional digital readout.
Q: What materials can be tested with this Vickers Hardness Tester?
A: This instrument is suitable for testing a wide range of materials including metals, alloys, carburized or treated surfaces, ceramics, and thin sheets. Its adjustable load and flexible dwell time make it ideal for both micro and macro hardness assessments across these materials.
Q: When should the indenter or weights be replaced?
A: Replace the Vickers diamond indenter or standard weights if you notice visible wear, damage, or inconsistent test results. Regular inspection and calibration as per ASTM E92 or IS:1754 standards are recommended to maintain accuracy.
Q: Where should the tester be installed for optimal operation?
A: Install the Vickers Hardness Tester on a stable, level bench-top within a controlled environment-ideally at 10C to 35C temperature and up to 85% non-condensing humidity. Ensure the machine is positioned close to a 220 V AC, 50 Hz power supply for reliable operation.
Q: What is the typical process for conducting a hardness test?
A: Place a single specimen on the stage (max. height 60 mm, width 55 mm) and secure it. Select the appropriate load and dwell time, lower the indenter manually to make the impression, and then use the optical microscope to measure the diagonal of the indentation for an immediate determination of Vickers hardness value.
Q: How does this tester ensure accuracy and user safety?
A: Accuracy is assured with a precision diamond indenter, a microscope scale resolution of 0.1 micron, and compliance to major test standards. Overload protection safeguards the indenter during operation, while durable powder-coated and stainless steel construction enhances longevity and safety.
Q: What are the benefits of using this Vickers Hardness Tester in a laboratory or industrial setting?
A: This equipment offers reliable, precise, and standardized hardness measurement for varied applications, enhancing quality assurance processes. Its manual control ensures flexibility, and its robust design makes it suitable for both routine laboratory analysis and demanding industrial environments.
