Product Overview

The MH180 Portable Leeb Hardness Tester from MITECH is a compact, reliable, and easy-to-use hardness testing instrument designed for fast, on-site measurement of metallic materials.
Based on the Leeb rebound hardness principle, the MH180 enables non-destructive hardness testing directly on large, heavy, or installed components where traditional bench testers are impractical.

With automatic hardness scale conversion, a high-contrast LCD, and long battery life, the MH180 is an ideal solution for production inspection, maintenance, failure analysis, and material identification.

Key Features

• Based on the Leeb hardness testing principle for quick on-site measurements
• Measures a wide range of metallic materials
• Automatic conversion between HL, HB, HRC, HRA, HV, and HS scales
• High-contrast segment LCD for clear readability
• One main unit compatible with up to 6 different impact devices
• D-type impact device supplied as standard
• Supports steel identification – displays HB value directly for steel
• Automatic calibration for reliable accuracy
• Stores 100 groups of measurements (with average and single values)
• Displays test data including date/time, impact direction, material, hardness scale
• Long battery life – over 100 hours standby time
• Compact, lightweight, and rugged design for field use
• Optional PC software for data transfer, analysis, and reporting
