Mikrosize Leeb Hardness Tester Series
Developed by Mikrosize, a top supplier of precision testing equipment, our series of Leeb hardness testers features innovative design and stable, dependable performance. All models in this series adopt D-type impact probes with an upgraded ergonomic structure, delivering outstanding portability and full one-handed operability. Users can easily carry and operate the tester both in production workshops and laboratories.
To optimize user experience, the tester is fitted with a large high-contrast dot-matrix OLED screen paired with a reworked UI and responsive physical keys. This setup delivers crisp, legible measurement readouts, enabling instant data viewing under strong sunlight or low-light environments alike. Built-in Bluetooth connectivity supports instant data printing via a compact Bluetooth printer. It also supports data transmission to a dedicated mobile test data app (currently in development and unavailable at present) for convenient storage and post-processing, broadening its applicable scenarios.
The standard Leeb hardness tester, our flagship testing device, comes preloaded with hardness conversion charts for mainstream materials. It also supports tensile strength calculation and switching to international hardness conversion scales, covering an ultra-wide testing range to satisfy cross-industry demands. Whether for automotive manufacturing, mechanical processing or metal material research, this standard model delivers accurate, efficient hardness testing solutions.
Built upon the standard model, our power-industry dedicated hardness tester is custom-developed for power plants and adds test parameters for nine widely used high-alloy steels in power equipment. It fully complies with the power industry standard DL/T 1845-2018 Leeb Hardness Test Method for High-Alloy Steel in Power Equipment, delivering high professional suitability for power sector work. It has become an essential inspection tool for power equipment manufacturing, maintenance and quality control, helping enterprises boost test accuracy and working efficiency.
A standout feature of our Leeb tester series is the custom material calibration function. Users may generate personalized hardness conversion charts via comparative testing, effectively resolving the common issue of inaccurate readings and large deviations caused by generic preloaded conversion charts. This function greatly improves the tester’s flexibility and measuring precision, making it suitable for testing special materials not covered by standard conversion charts.
Beyond the above functions, the tester series includes many other practical user-oriented features. Its compact body delivers superior portability for easy transport and operation in confined spaces. The 128×64 dot-matrix OLED screen presents full test data with excellent visualization. It also features automatic identification of standard impact directions to cut operating errors and boost test efficiency.
For batch inspection tasks, the device stores average values from up to 100 measurements. Users may preset upper and lower hardness thresholds with automatic out-of-spec alerts to streamline batch testing and quality control. As a multi-functional tester, it supports switching to international hardness conversion scales for reference, catering to international projects and cross-border collaboration. It also supports software-based indication calibration to sustain long-term measuring precision without frequent hardware tweaks.
To simplify data management, the tester wirelessly connects to Bluetooth printers for instant hard-copy test records. Bluetooth pairing with a dedicated mobile measurement app unlocks extended functions (reserved for future firmware upgrades) for smarter, more streamlined operation. An adjustable auto power-off function is built in for power conservation; users may modify the delay time or disable the function entirely.
The tester runs on an internal rechargeable lithium-ion battery with a Type-C charging port. The battery features zero memory effect for easy charging and an extended service life, eliminating frequent battery replacement, lowering maintenance costs and supporting uninterrupted work. Our power-dedicated hardness tester complies with industrial standards and supports testing on nine mainstream high-alloy steel workpieces, making it a reliable pick for power industry practitioners.
To sum up, Mikrosize’s Leeb hardness tester series is a premium testing device integrating portability, high precision and comprehensive functionality. Both the universal standard model and power-industry dedicated variant deliver stable, efficient hardness testing solutions for end users. Backed by Mikrosize’s consistent focus on quality and technological innovation, this product line serves as an indispensable tool for material hardness inspection.
