Digital Brinell Hardness Tester
Mikrosize Digital Brinell Hardness Tester is a high-end hardness testing instrument manufactured by Mikrosize, a trusted supplier of precision metal hardness testing equipment. This advanced tester delivers accurate, repeatable hardness measurement results, serving as essential quality control equipment across industries with strict material hardness inspection requirements.
Core Structural Advantages
The entire test procedure supports real-time screen display full process visual Brinell hardness tester,allowing operators to monitor every testing step for guaranteed measurement accuracy. The tester maintains constant stable test force throughout the cycle, delivering outstanding repeatability — a critical indicator for consistent, reliable hardness test data.
The machine frame adopts one-piece cast iron forming, followed by long-duration stress relief aging treatment. This process thoroughly eliminates internal residual stress inside the frame, resulting in rigid, high-strength construction with excellent durability. Even under harsh working environments including freezing winter temperatures, intense summer sunlight, strong wind and heavy rain, the frame stays intact without deformation, ensuring stable long-term operation.
Electrical & Operating System Upgrades
The unit has undergone medium-term hardware upgrades to boost functionality and user experience, fitted with a 5.6-inch color touch screen. The intuitive interface integrates comprehensive functions to satisfy diverse testing demands.
Equipped with a built-in hardness conversion module, the tester automatically converts Rockwell (HR) and Vickers (HV) hardness values to Brinell (HBW), and calculates the ultimate tensile strength (Rm) of test materials. This all-in-one conversion function eliminates manual calculation and external tools, significantly improving testing efficiency.
Intelligent on-screen menu prompts guide users through every operation step, lowering the learning threshold for both senior technicians and new operators. This user-oriented design reflects Mikrosize’s focus on practical, easy-to-operate hardness testing equipment.A built-in thermal printer enables instant output of hardness test reports for easy filing, archiving and sharing for quality control documentation. USB and RS232 communication ports are integrated for seamless data transmission between the tester and computers or data storage devices, greatly optimizing data management workflows.
Optional Automatic Imaging System
For customers requiring higher automation, an optional CCD automatic image processing system is available. The system automatically captures and analyzes indent impression images, minimizing human measurement error while lifting overall testing efficiency and precision.The tester features an innovative yet robust structure, combining modern appearance with heavy-duty construction to withstand daily industrial use. Its high testing throughput enables mass sample inspection without compromising data accuracy. All test results comply with global authoritative standards: GB/T231.2, ISO6506-2 and ASTM E10, making test data universally recognized worldwide.
Application Scope
This Brinell hardness tester delivers versatile material testing capacity, designed to measure the Brinell hardness of ferrous metals, non-ferrous metals and bearing alloys. It is widely adopted in automotive manufacturing, aerospace engineering, general machinery fabrication and metal processing sectors. It performs exceptionally precise measurements on flat-parallel specimens, providing reliable hardness data to evaluate material quality and mechanical performance.
