Color Screen Leeb Hardness Tester: Portable Hardness Testing with Mikrosize iLeeb-300
In industrial inspection and quality control, a portable hardness tester that combines high performance, ease of use, and adaptability to multiple scenarios brings significant efficiency gains to production, maintenance, and material management. The iLeeb-300 Color Screen Leeb Hardness Tester from Mikrosize is a detection device that integrates robust hardware design, advanced processing capabilities, and versatile application support. Whether inspecting mold cavities, evaluating heavy workpieces, or performing rapid material differentiation in warehouses, this portable Leeb hardness tester delivers reliable results with exceptional user convenience.
Intuitive Hardware Design for Simplified Operation
The iLeeb-300 is designed with clarity and user-friendliness at its core. The main unit incorporates an impact device connector, a vivid color LCD screen, and a well-organised keypad. The impact device itself consists of a release button, loading sleeve, conduit, coil component, impactor, and supporting ring—each component working in smooth coordination to generate consistent impact energy.
The high-quality color LCD screen displays up to 10 key parameters simultaneously, including measurement values, time, battery level, and measurement count, allowing inspectors to grasp all critical information at a glance. The 9 dedicated keys on the keypad provide direct access to essential functions such as material selection, hardness scale selection, data storage, statistics, and waveform viewing. This intuitive layout eliminates complex operating procedures, significantly lowering the learning curve for new users and enabling rapid deployment in demanding inspection environments.
High-Performance Processing and Advanced Measurement Capabilitie
At the core of this Leeb hardness tester lies a high-performance ARM processor with a Cortex-M4 core, delivering extremely fast computing speeds for real-time hardness value calculation and data processing. This powerful processing capability ensures that measurement results are displayed almost instantaneously, enhancing overall inspection efficiency.
The probe features automatic identification with plug-and-play technology—unlike other manufacturers’ devices that require probe connection before power-on, the iLeeb-300 recognises the probe automatically upon connection, simplifying the pre-inspection preparation process and saving valuable time.
A standout feature of the iLeeb-300 is its unique full-scale display capability. The main interface simultaneously shows hardness values across all scales—Leeb (HL), Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Vickers (HV), and Shore (HS)—without the need for users to consult conversion tables or switch interfaces repeatedly. This makes comparative data analysis more intuitive and efficient.
The instrument also supports impact waveform analysis, displaying the Leeb hardness impact waveform to help operators judge the validity of each test and assess the working condition of the impact device—for example, whether the probe is worn or whether dirt has accumulated inside the housing. This diagnostic capability ensures data reliability and extends the service life of the probe.
Flexible Data Management and Connectivity
The iLeeb-300 provides comprehensive data management features. It can store up to 100 groups of hardness measurement data (with each group containing 32 to 1 impact times). Each data group includes individual measurement values, average values, impact direction, number of impacts, material type, and hardness system, providing a complete record for traceability and reporting.
Data transfer is supported via USB communication, with upper computer data processing software included as standard. For on-site reporting, the instrument offers Bluetooth printing capability—users can optionally equip a Bluetooth printer to output test results immediately without the need for data transfer back and forth. Three viewing modes—data, graphics, and tables—allow testers to select the most suitable format for their analysis needs.
Battery Life and Portability
Power supply is handled by two AA alkaline batteries, providing continuous operation for no less than 50 hours on a single set. The instrument incorporates power-saving features including automatic sleep and automatic shutdown, ensuring that the device is always ready for use when needed. The compact dimensions of 150×76×37 mm and weight of only 245 g make the iLeeb-300 exceptionally portable, ideal for factory workshops, outdoor sites, and confined spaces where access is limited.
Wide Application Versatility
The iLeeb-300 supports testing of a broad range of metal materials, including steel and cast steel, alloy tool steel, cast aluminium alloy, grey cast iron, nodular cast iron, stainless steel, copper-zinc alloy (brass), copper-tin alloy (bronze), and pure copper. The measurement range spans 170 to 960 HLD, and the instrument supports five impact directions: vertical downward, oblique downward, horizontal, oblique upward, and vertical upward.
Key applications include:
- Mould cavities and bearing components—precise hardness verification of critical parts
- Failure analysis of pressure vessels and turbine generator sets—non-disruptive testing without disassembly
- Heavy workpieces and installed machinery—hardness evaluation without removing components
- Confined spaces—testing inside pipes, narrow gaps, and other limited-access areas
- Material differentiation in metal warehouses—rapid classification using hardness characteristics
- Large-scale rapid inspection—multi-point testing across extensive workpieces
Technical Specifications
The standard impact device is Type D, with optional impact devices including D, C, DC, D+15, DL, E, and G available for specialised applications. The instrument operates in temperatures ranging from –10 °C to +50 °C, with storage temperatures from –30 °C to +60 °C, and relative humidity ≤90%. With its robust construction and vibration, shock, and electromagnetic interference resistance, the iLeeb-300 is built for demanding industrial environments.
From precision parts inspection to large-scale equipment failure analysis, the iLeeb-300 Color Screen Leeb Hardness Tester delivers the performance, portability, and intelligence required for modern industrial hardness testing.
