Product Description
PROLH210 Portable Leeb Hardness Testers are used to determine one of a material's critical mechanical properties, hardness. Hardness testing can be performed with either classic desk-mounted testers or with the more modern portable testers. The reliability and accuracy of static and portable hardness testers are investigated in this study. Our leeb hardness testing device range describes four unique methods for determining the hardness of calibration hardness plates. To determine measurement accuracy, hardness values were contrasted to the reference hardness specified on the calibration hardness plates. The study compared the reliability and accuracy of portable hardness testers to those used on desks.

Leeb Hardness Tester FAQ:
Q. What is a Leeb hardness testind device?
Ans: A Leeb hardness tester is a portable device used to measure the hardness of metals. It operates based on the rebound principle, where a small, hard indenter is propelled against the surface of the material under test. The rebound velocity is measured and converted into a hardness value.
Q. How does a Leeb hardness tester work?
Ans: When the impact body of the tester strikes the surface of the material, it rebounds back, and the device measures the velocity of this rebound. This velocity is then converted into a hardness value using calibration curves specific to the material being tested.
Q. What are the advantages of using a Leeb hardness tester?
Ans: Below are some of it's advantages
a. Portability: Leeb hardness testers are usually handheld and battery-powered, making them suitable for use in various locations.
b. Quick results: Measurements can be taken rapidly, allowing for efficient testing in different areas.
c. Non-destructive: Unlike some other hardness testing methods, Leeb testing does not typically damage the material being tested.
d. Suitable for various materials: Leeb hardness testers can measure the hardness of metals, including steel, aluminum, and other alloys.
Q. What are the limitations of Leeb hardness testers?
Ans: Below are some of it's limitations:
a. Surface finish: The surface finish of the material being tested can affect the accuracy of measurements.
b. Calibration: Proper calibration is essential for accurate results, and different materials may require specific calibration curves.
c. Material thickness: The thickness of the material can impact the accuracy of measurements, particularly for thin materials.
d. Anisotropic materials: Leeb hardness testers may not be suitable for measuring the hardness of materials with varying properties in different directions.
Q. How do I calibrate a Leeb hardness tester?
Ans: Calibration typically involves using reference blocks with known hardness values that are similar to the material being tested. The device is adjusted to match the readings obtained from the reference blocks, ensuring accurate measurements.
Q. Can a Leeb hardness tester measure the hardness of welds?
Ans: Yes, Leeb hardness testers can measure the hardness of welds. However, it's essential to consider factors such as surface preparation and the presence of heat-affected zones, which can affect the accuracy of measurements.
Q. Are there different types of Leeb hardness testing device?
Ans: Yes, there are various models and brands of Leeb hardness testers available, ranging from basic handheld devices to more advanced models with additional features such as data logging and wireless connectivity.
