Engineered for precision hardness testing, the pen-type Leeb hardness tester is a standout industrial device manufactured by Mikrosize, a reputable supplier of premium testing equipment for all industrial sectors. Built to satisfy diverse material testing requirements, it delivers reliable performance, outstanding portability and advanced functions for routine and professional inspection tasks alike.
Product Overview: Top-Tier Testing Device by Mikrosize
All units come fitted with a Type D impact probe, a critical component that guarantees stable, repeatable and accurate test readings. Its redesigned ergonomic body is its standout advantage: ultra-portable for field testing and partially operable with one hand, greatly boosting efficiency during heavy workloads.
In terms of human-machine interaction, the tester adopts a high-contrast 128×64 dot-matrix OLED screen. Matched with a brand-new UI layout and responsive physical keys, the screen presents complete test data, hardness values and status signals clearly even under dim light environments. Equipped with built-in Bluetooth, it gains an edge over conventional hardness testers. This enables real-time data output via a mini Bluetooth thermal printer; alternatively, data can be sent to Mikrosize’s dedicated inspection mobile APP (optional accessory) for secure storage, in-depth analysis and post-processing. This complete data management workflow makes the unit ideal for modern inspection jobs requiring full data traceability and high efficiency.
Enhanced Professional Version: Custom Hardness Tester Optimized for the Power Industry
Based on the mature standard model, Mikrosize has launched a professional variant specially optimized for power sector scenarios. This upgraded unit preloads 9 dedicated hardness conversion curves for high-alloy steel widely used in power generation equipment, fully complying with DL/T 1845-2018 Leeb Hardness Test Method for High-Alloy Steel in Power Equipment. This targeted customization delivers reliable hardness measurement data for high-alloy steel components including steam turbines, generators and pressure pipelines, widely applicable to power plants, electrical equipment manufacturing and equipment maintenance. For power industry practitioners, this tester is more than a measuring tool, but a dependable solution that fulfills specialized industry testing standards.
Custom Material Calibration Function: Versatile Testing Equipment by Mikrosize
One of the most well-received highlights of this tester is its custom material calibration feature, which solves a long-standing pain point in material inspection. Conventional hardness testers only rely on factory preset conversion curves, which cause inaccurate readings and significant measurement deviations when testing non-standard or special alloys. To resolve this issue, users can create exclusive hardness conversion curves via comparative calibration with certified reference blocks. After comparative testing against standard samples of target materials, the tester can be calibrated to match the unique mechanical properties of tested workpieces, delivering precise, material-adapted hardness results every time. Thanks to this flexibility, the tester fits a broad range of industries including automotive, aerospace, metallurgy and general manufacturing, where customized testing schemes for various materials are required.
Working Principle of Mikrosize Pen-Type Leeb Hardness Tester
This pen-type Leeb hardness tester operates on the mature, decades-proven Leeb hardness measurement principle. Its working mechanism is as follows:
An impact body with fixed mass is accelerated by elastic force to hit the surface of a test sample at a preset velocity. When the impact body is 1 mm away from the sample surface, the tester’s high-precision sensors capture two core parameters: pre-impact velocity VA and rebound velocity VB of the impact body. The built-in core algorithm calculates the Leeb hardness value (HL) via the formula below:
HL = 1000 × VB ÷ VA
Where:
HL = Leeb hardness value (primary reading displayed on the tester)
VB = Rebound velocity of the impact body (captured by high-precision built-in sensors)
VA = Pre-impact velocity of the impact probe (calibrated during factory production)
This measurement principle ensures objective, repeatable hardness readings that truly reflect the mechanical characteristics of tested materials.
