Professional hardness evaluation instruments conforming to ASTM and ISO standards. Supporting Rockwell, Micro/Macro Vickers, Brinell, Universal, and Portable testing solutions.
Hardness testers are precision testing instruments used to determine the surface hardness of materials. Material hardness represents a material's ability to resist the indentation of external forces, plastic deformation, wear, and scratching, serving as a core index for evaluating mechanical properties.
Hardness testers are primarily used for incoming material inspection, production quality control, finished product outgoing inspection, heat treatment effect verification, and product failure analysis, and are widely applied across various industries.
Depending on the model and testing principle, they can test various metal materials such as steel, cast iron, aluminum alloys, and copper alloys, and optional models are also available for testing non-metallic samples such as plastics, rubbers, and composite materials.
Different devices support different hardness scales: Leeb (HL), Rockwell (HRA/HRB/HRC), Brinell (HB), Vickers (HV), and Shore hardness, adapting to various workpieces and testing standards.
Portable hardness testers enable on-site non-destructive testing for large, non-detachable workpieces, while benchtop hardness testers are suitable for high-precision measurements of small laboratory samples.
Mikrosize hardness testers are specialized material hardness testing equipment designed for the industrial quality inspection sector. All products in the series are manufactured in strict compliance with universally recognized international testing standards, catering to material hardness testing demands across all industries. Equipped with diverse testing principles, the brand's core devices utilize indentation testing technology. By applying precisely controllable load pressure to the tested material, hardness parameters are accurately calculated based on indentation deformation data. Additionally, rebound-type testing mode devices are available to suit large workpieces and rapid on-site testing scenarios. Furthermore, high-end portable models integrate advanced ultrasonic testing technology to achieve low-loss, high-precision inspection. With flexible switching between multiple testing modes and relying on the equipment's mature technical configuration, they can deliver stable and precise hardness testing operations for various materials.

| Testing Method | Hardness Symbol | Core Principle | Applicable Materials & Working Conditions | Governing Standards | Adapted Mikrosize Testers |
|---|---|---|---|---|---|
| Rockwell | HR-A / HR-B / HR-C and other multiple scales | Applies a specified test force and measures the depth of indentation to calculate hardness. | Metal samples, suitable for larger workpieces; high testing efficiency, most widely applied. | ASTM E18, ISO 6508, JIS Z 2245 | Benchtop Rockwell Hardness Tester Series |
| Brinell | HBW | Applies a load via a cemented carbide ball indenter and measures the indentation diameter to calculate hardness. | Castings, forgings, non-ferrous metals, materials with coarser grains; suitable for coarse-grained material testing. | ISO 6506, ASTM E10 | Benchtop Brinell Hardness Tester |
| Vickers | HV | Uses a diamond square-pyramid indenter, calculates hardness via the diagonal length of the indentation; applicable to both micro and macro loads. | Almost all metal materials; thin sheets, coatings, heat-treated thin layers, and hard samples can all be tested. | ISO 6507, ASTM E384 | Micro / Large-Screen Digital Display Vickers Models |
| Leeb | HL-D / HL-S / HL-E / HL-C / HL-G | Measures the rebound velocity of an impact body and converts it into hardness based on rebound height. | Large on-site workpieces, heavy metal components that are difficult to move; the preferred choice for portable on-site testing. | ISO 16859, ASTM A956 | Full Series of Portable Leeb Hardness Testers |
| UCI (Ultrasonic) | HV (UCI) | Modified Vickers principle, evaluates the indentation area via ultrasonic impedance; classifies as a micro-damage inspection method. | On-site workpieces, roll surfaces, polished surfaces; unaffected by testing direction, capable of testing assembled components. | ASTM A1038, DIN 50159 | Portable UCI Ultrasonic Hardness Tester |
| Shore | HS-A / HS-D / HS-0 and other scales | Measures the depth of indentation by the indenter. | Plastics, rubbers, and various elastomeric non-metallic materials. | ISO 868, ASTM D2240 | Mikrosize Shore Hardness Tester (Rubber and Plastic Testing) |
| Barcol | HBa | Indentation depth method, enabling rapid testing under light load. | Aluminum profiles, aluminum alloy sheets, thin-walled non-ferrous metal parts. | ASTM B648 | Mikrosize Barcol Portable Testing Device |
Various hardness testing technologies possess distinct technical characteristics and application scenarios, enabling targeted solutions for testing challenges under different operating conditions.
Brinell and Rockwell testing technologies rely on standard gravity loading operations, offering strong testing stability with regular and uniform indentations, making them widely used for batch hardness testing of conventional metals and large workpieces.
Vickers testing provides exceptional precision and a wide material adaptation range, but is better suited for small laboratory sample testing, failing to meet on-site testing demands for large stationary equipment or fully assembled finished products.
Commonly used Leeb testing equipment is suited for outdoor operations due to its portable and efficient advantages, though conventional errors may occur during multi-scale value conversion. Ultrasonic hardness testers adopt the mainstream industry-standard UCI (Ultrasonic Contact Impedance) testing process, creating extremely minute test indentations to achieve near non-destructive testing, thereby maximizing the integrity of the tested workpiece. Backed by core advantages of high precision, non-destructive operation, and high stability, this series of high-end models is positioned for high-end precision quality inspection scenarios, adapting to rigorous industrial testing standards.
The entire series of Mikrosize hardness testers features an ergonomically optimized design, offering a portable and lightweight body with simplified operating procedures. This significantly enhances operational efficiency in scenarios such as industrial production, quality control, equipment operation and maintenance, and on-site technical inspection, demonstrating outstanding industrial practicality. Supported by a comprehensive product line of testing equipment, Mikrosize provides all-material hardness testing solutions, capable of precisely inspecting conventional and special materials such as metals, plastics, rubber, composite panels, concrete, and leather.
The devices support the vast majority of mainstream hardness measurement units on the market, including Shore (HS), the full series of Rockwell scales, Brinell (HB), Vickers (HV), Leeb (HL), Barcol (HBA), Webster (HW), and international standard MPa (N/mm²) units, accommodating all types of industry testing specifications. Products are categorized into mechanical dial types and intelligent digital display types. Dial types are equipped with a 360° visible scale plate for clear readings from any angle; digital display types feature a high-definition LCD screen for real-time visual display of testing data. Most smart models have built-in high-capacity data storage modules and high-speed USB transmission interfaces, supporting one-click export, archiving, and PC-side data analysis of testing data, making it convenient for enterprises to build standardized quality inspection data systems.
Mikrosize portable series hardness testers come standard with a high-capacity built-in rechargeable battery, delivering robust endurance and the ability to operate for extended periods away from external power sources. This perfectly suits scenarios such as workshop work-stations without power access, outdoor on-site testing, and field inspections. Equipped with an integrated rebound testing structure and a wireless all-in-one design, they completely eliminate the constraints of traditional cables, effectively avoiding issues such as cable aging, poor contact, and line entanglement. This prevents testing errors from a hardware level, making testing operations more convenient, stable, and efficient while substantially improving on-site quality inspection efficiency.
