Leeb Hardness Tester | Portable Metal Hardness Gauge for Large Workpieces

Advanced Leeb Hardness Tester: A Comprehensive Solution for Industrial Hardness Testing

The Leeb hardness tester stands as a pivotal instrument in the modern industrial landscape, offering a portable, versatile, and highly reliable method for determining material hardness. As a premier Measuring Testing Instrument, its design is centered on overcoming the limitations of traditional, stationary hardness testers. Its operation is streamlined through an intuitive, menu-based operation system, allowing operators of varying experience levels to perform accurate measurements with minimal training. This user-friendly interface is a hallmark of its sophisticated design, ensuring that critical data is always accessible and easy to manage.

A key feature that underscores its adaptability is its flexible connectivity. The tester is equipped with either a Type-C USB or an RS485 communication interface, providing robust options for data transfer and device charging. This versatility is further amplified by its unique compatibility with a diverse range of impact devices. The instrument can be equipped with up to 7 different impact devices, each designed for specific applications and material types. A significant technological advantage is that these impact devices do not require recalibration when replacing one for another, as the tester can automatically identify the type of impact device connected. This seamless integration drastically reduces downtime and enhances testing efficiency in dynamic workshop or field environments.

When sourced from a trusted supplier like Mikrosize, users can be assured of a device that delivers exceptional performance and data integrity. The tester supports measuring multiple hardness systems (such as HL, HRC, HB, HV, etc.) and can even convert readings to three different strength values, making it an indispensable tool for engineers and quality control professionals. For data management, it offers substantial internal storage, capable of holding between 373 to 2688 sets of data. Each set can include single measurement values, averages, measurement dates, impact directions, number of impacts, material types, and hardness system information, providing a comprehensive audit trail for quality assurance.

To streamline high-volume production checks, this Measuring Testing Instrument allows for the pre-setting of upper and lower hardness limits. The system will trigger an automatic alarm when a measurement exceeds these limits, providing immediate feedback for batch testing and ensuring only components within specification proceed. Furthermore, the instrument features a calibration function of indication software to maintain long-term accuracy, which is verified to meet stringent standards such as GB/T 17394.2. Powering these advanced features is a built-in high-performance lithium battery and an intelligent charging control circuit, engineered for ultra-long working and standby times to support extended shifts and remote operation.

The capabilities of the Leeb hardness tester are fully realized when connected to a broader data ecosystem. It can be equipped with dedicated computer software, enabling powerful functions such as advanced data query, secure long-term storage, statistical analysis, and intuitive bar chart displays for trend visualization. For immediate reporting, the device incorporates a built-in thermal print head, allowing for the real-time printing of measurement data, which is both convenient and fast for on-the-spot documentation. As a product available through Mikrosize, customers receive not only the hardware but also a complete solution backed by expert support.

The application scope of the Leeb hardness tester is remarkably broad. It is primarily used to measure the Leeb hardness of black and non-ferrous metal materials. Its portability makes it the ideal choice for measuring large, heavy workpieces or installed permanent components that cannot be transported to a lab. It is also the go-to solution for hardness measurement in areas that are difficult to access with a desktop hardness tester or within confined and narrow spaces, proving its unmatched utility in fields ranging from metal manufacturing and welding inspection to aerospace and power generation maintenance.
