WUHU, China - Oct. 22, 2026 - PRLog -- Mikrosize, a global supplier of precision measurement and testing instruments, announced the launch of its iBRRV‑187.5 Digital Brinell Rockwell Vickers Hardness Tester, an all‑in‑one system for reliable material inspection.
Separate testers are traditionally needed for Brinell, Rockwell and Vickers tests, raising cost, space and labour demands. The iBRRV‑187.5 integrates the three test methods in one unit. Its electronic closed‑loop loading removes manual weight changes and delivers stable, repeatable force control. It features an 8‑inch touchscreen, multi‑scale optical indentation measurement and data interfaces, serving manufacturers, labs, research institutes and third‑party test agencies.
Key Technical Features and Highlights of the iBRRV‑187.5
- Three‑in‑One Hardness Testing: The iBRRV‑187.5 supports Brinell, Rockwell and Vickers tests in one instrument. Operators switch modes on screen to cut extra testers and simplify lab workflows.
- Electronic Closed‑Loop Loading: Stepper motor and force sensor replace dead weights for electronic force regulation. It removes frequent weight swapping for better accuracy and repeatability, with dwell time adjustable 0‑90 seconds.
- Large Touchscreen and Multi‑Language Interface: The 8‑inch touchscreen supports Chinese, English and Russian. Built‑in hardness conversion allows fast cross‑scale comparison.
- Clear Optical Indentation Measurement: The integrated optical system captures sharp Brinell and Vickers indent images. Dual‑lighting options reduce visual reading errors for consistent results.
- Data Management and Connectivity: Test results store internally. A thermal printer generates reports; USB and RS232 ports connect to PCs for data export and custom reporting.
The tester covers three core application scenarios. It handles incoming and in‑process QC for auto parts, molds, castings, heat‑treated components, bearings and fasteners. Labs use it for alloy comparison, heat‑treatment assessment and material property analysis. It also supports failure analysis by detecting hardness variation from decarburization, overload and heat‑treatment defects.
Its measurement ranges: Rockwell 20‑88 HRA, 20‑100 HRB, 20‑70 HRC; Brinell 5‑650 HBW; Vickers 10‑2900 HV. Optional CCD modules, software, fixtures, hardness blocks and indenters are available.

The iBRRV‑187.5 is available worldwide through Mikrosize and its authorized distributors. Mikrosize provides calibration documents, operator training and technical support for stable long‑term operation. The brand serves customers in over 40 countries and expands its global service network continuously.
