Hardness tester devices, displayed at the site: https://www.hardnessgauge.com, can determine hardness using a typical method of assessment. The principle of these hardness tester tools is dependent on the dissemination of a diamond indenter into the test object or a computation in relation to the rebound force after hitting the test object. However, the hardness of the objects can be detected precisely using ultrasonic testing as well. Every hardness testing procedure has its pros and can precisely assess the material hardness following the practical requirements of the appropriate hardness tester.
For instance, Rockwell and Brinell hardness assessment methods make use of a powerful force to develop a huge indentation on the external portion of the test object. The Vickers hardness testing method integrates optical measurement however it cannot be applied on mounted equipment as well as perpetually assembled components. Leeb hardness testers apply both indirect and rebound methods to determine hardness. Moreover, they cause considerable deviations while switching from Leeb to Rockwell, Vickers, and Brinell hardness scales. However, ultrasonic hardness testers make use of a highly precise ultrasonic contact impedance (UCI) approach to determine the hardness, by leaving a tiny dent in the external part of the test object. Still, because of the nondestructive nature and high degree of accuracy by measuring via an ultrasonic hardness tester, the cost of the equipment is comparatively higher.
Due to their ergonomic design and easy portability, these hardness testers can be applied in production, manufacturing, technical services, and quality assessment. They are mostly used in the tooling industries. On our site, you can find a vast range of best quality hardness tester devices to figure out the hardness of every object such as metal, rubber, plastic, steel, leather, concrete, and many more.
According to the type, a hardness tester determines hardness in Rockwell (HRA / HRB / HRC / HRD / HRE / HRF / HRG / HRH / HRK / HRN / HRT), Vickers (HV), Brinell (HB), Shore (HS), Leeb (HL), Webster (HW), Barcol (HBA), or MPa (N/mm²) SI units. A mechanical hardness tester or an analog has a 360-degree dial, whereas a digital hardness tester consists of an LCD screen. Several digital hardness testers provide data logging abilities including features such as an internal memory or a USB port for transferring data to the computer.
Diamond hardness testers include a wide range of hardness testers from Rockwell, Vickers, and Brinell to fully automatic production systems along with ISO test blocks, accessories, and fixtures. Hence, our calibration laboratory is considered the universal leader in the manufacture of premium ISO indenters as well as test blocks.

The Rockwell test is comparatively easier to perform and more precise than other hardness testing methods. The Rockwell test method can be used on all metals, except in the condition where the test sample structure or surface conditions would bring too many variations; where the indentations can be too large; or where the sample size or shape may prohibit its use.
The Brinell hardness test method follows ASTM E10 standards to inspect the materials whose structure is too coarse or having a rough surface that can be tested using another method such as castings and forgings. This test often uses a very high test load (3000 kgf) as well as a 10mm diameter indenter where the resultant indentation averages out most of the surface and sub-surface inconsistencies.
The Vickers hardness test method, otherwise called a microhardness test method, is used for small objects, thin sections, as well as the case depth work. Due to the small indentation in a Vickers test, it can test very thin materials like foils, small parts, small areas, or the surface of a part, and individual microstructures. It can also figure out the depth of hardening by sectioning apart and creating a series of indentations to find the change in hardness. This method can evaluate almost any type of material such as ceramics, metals, and composites as well.
The Leeb hardness testing, otherwise called as Leeb Rebound Hardness Test (LRHT), is considered as one of the four commonly used methods to test the hardness of the metal. It is a type of non-destructive testing used to inspect large sized workpieces weighing above 1 kg. It also measures the coefficient of restitution.
