The LHBRV-187.5DX adheres to rigorous standards like GB/T230.2 for Rockwell testing. It aligns with ISO 6508-2 and ASTM E18 for global consistency. JIS Z2245 compliance further ensures its reliability across international markets.

Hardness Tester Testing Capabilities

Rockwell testing applies forces of 60 kgf (588 N), 100 kgf (980 N), and 150 kgf (1471 N). Brinell ranges from 15.625 kgf (153.2 N) to 187.5 kgf (1839 N). Vickers offers 5 kgf (49.3 N) to 100 kgf (980.7 N), accommodating a wide variety of materials and test conditions.

Hardness Tester Scales and Measurement Ranges

It supports Rockwell scales like HRA, HRB, and HRC, with ranges of 20-90 HRA, 20-100 HRB, and 20-70 HRC. Brinell scales include HBW2.5/15.625 to HBW2.5/187.5, measuring 5-650 HBW. Vickers scales (HV5 to HV100) cover 5-3000 HV, offering comprehensive testing flexibility.

Hardness Tester Physical Specifications

The unit measures 550×230×780 mm and weighs approximately 85 kg, making it compact yet robust. It accommodates specimen heights up to 180 mm for Rockwell and 165 mm for Brinell and Vickers. A 160 mm distance from indenter to outer wall enhances accessibility during testing.

Hardness Tester Optical Precision

With magnifications of 25X, 50X, and 100X, this tester ensures detailed inspection. It includes a 10X digital eyepiece and objectives of 2.5X, 5X, and 10X. These optics provide clear, accurate views of hardness indentations, critical for quality control.

Hardness Tester Data Management

A built-in thermal printer delivers immediate test results for on-site analysis. An RS232 interface allows connection to computers for data logging and analysis. Conversion scales enable easy comparison across different hardness standards.

Hardness Tester Material Applications

This tester excels with ferrous and non-ferrous metals. Brinell is ideal for castings, annealed steel, and soft alloys. Rockwell suits heat-treated materials, while Vickers handles nitriding layers, ceramics, thin sheets, and plated coatings.

Hardness Tester Industry Use Cases

Steel manufacturers rely on it to verify material strength and consistency. Automotive plants test components like gears and shafts for durability under stress. Plating and ceramic industries use it to assess thin layers and small parts with high precision.

Hardness Tester Standard Accessories

The package includes diamond indenters for Rockwell and Vickers testing. It provides a 1.5875 mm ball indenter and 2.5/5 mm Brinell indenters. Hardness blocks, large/medium/V-shaped testing tables, and a sliding bench are also included.
