Universal Hardness Tester – Frequently Asked Questions
1. What is a Universal Hardness Tester and how does it work?
A Universal Hardness Tester is a multi-functional material testing instrument capable of performing Brinell, Rockwell, and Vickers hardness tests on a single machine. It works by applying a controlled force (load) through a specific indenter into the surface of a material. The system then measures the depth or size of the indentation to determine the material’s hardness value, displaying results on a digital LCD screen.
2. Which hardness scales can the LAR-HBRV-187.5 measure?
The LAR-HBRV-187.5 is designed for versatility, covering:
-
Rockwell: Regular and Superficial scales.
-
Brinell: Ideal for materials with coarse structures or rough surfaces.
-
Vickers: Used for precision testing of thin sections and small parts. This "all-in-one" capability eliminates the need for multiple machines, saving laboratory space and equipment costs.
3. What are the key technical specifications of this hardness tester?
This model is built for high precision and features:
-
Initial Test Force: 98N (10Kgf).
-
Microscope Magnification: Dual settings at 37.5x and 75x for accurate Vickers/Brinell measurement.
-
Hardness Resolution: 0.1 HR (Rockwell).
-
Dwell Time: Adjustable from 1 to 60 seconds.
-
Max Specimen Height: 180mm (Rockwell) and 135mm (Vickers/Brinell).
4. Does this instrument comply with international testing standards?
Yes. The IDM Universal Hardness Tester complies with major international quality and safety standards, ensuring your data is globally recognized:
-
Brinell: ISO 6506, ASTM E10
-
Vickers: ISO 6507, ASTM E92
-
Rockwell: ISO 6508, ASTM E18
5. What are the benefits of an automatic hardness testing system?
The LAR-HBRV-187.5 features automatic operation and a digital encoder. This significantly reduces "human error" during the testing process, increases repeatability, and ensures high sensitivity. The built-in printer also allows for immediate, real-time technical data reports for quality control documentation.
6. What accessories are included with the Universal Hardness Tester?
The unit comes as a complete kit ready for immediate use, including:
-
120° Diamond Cone (Rockwell) and 136° Diamond Indenter (Vickers).
-
Ball indenters (Ø1.588mm Rockwell; Ø2.5mm and Ø5mm Carbide Brinell).
-
Standard Hardness Blocks for all three scales (Brinell, Rockwell, Vickers).
-
Large, small, and V-shaped test tables for various specimen shapes.
-
A measuring microscope and printing paper.
7. Can this machine test large or irregular samples?
Yes. With a throat depth of 140mm and a maximum specimen height of 180mm, the tester can accommodate a wide range of part sizes. The inclusion of V-shaped test units also allows for the stable testing of cylindrical or curved specimens.
8. Why should I choose a "dead-weight" vs. "load-cell" system?
IDM Instruments offers a range from traditional dead-weight models to advanced load-cell systems. Dead-weight systems are known for their long-term stability and reliability, while load-cell systems often offer faster testing cycles and easier calibration.
