The Digital Leeb Hardness Testing Machine is a portable metal hardness gauge engineered for steel, cast iron, aluminum, and copper alloy testing. Housed in a compact plastic case, it delivers reliable hardness measurement under demanding working conditions and at any angle, including upside down.

• Compact plastic case designed for use under poor working conditions; test at any angle, even upside down.
• Wide measuring range covering all metallic materials, with direct display of HRB, HRC, HV, HB, HS, and HL hardness scales.
• Large segment LCD screen showing all functions and parameters, with EL background light for low-light environments.
• Large-capacity memory capable of storing up to 100 groups of measurement information.
• Datapro software for PC connection via RS232 port, with micro printer support.
• Software calibration function for accurate, repeatable results.

• Measuring range: (170–960) HLD, (17.9–69.5) HRC, (19–651) HB, (80–1042) HV, (30.6–102.6) HS, (59.1–88) HRA, (13.5–101.7) HRB — customizable on request
