Product Overview The Mitech MH180 Portable Leeb Hardness Tester is a lightweight, compact, and cost-effective tool for on-site hardness testing of a wide range of metallic materials. Based on the Leeb hardness principle, it provides fast and reliable results with automatic conversion between hardness scales including Leeb (HL), Brinell (HB), Rockwell (HRC/HRB), and Vickers (HV). Its high-contrast LCD display, stable performance, and durable build make the MH180 an excellent choice for regular industrial use, failure analysis, and production quality control — offering great value without compromising reliability. Key Features Hardness Conversion: Supports HL, HB, HRB, HRC, and HV Compact & Lightweight: Designed for easy transport and field testing High-Contrast Segment LCD: For clear readability in any light Quick Impact Testing: Based on rebound velocity measurement Reliable Performance: Stable output with repeatable accuracy Affordable & Practical: Ideal for general-purpose industrial hardness testing Applications Die cavities and precision molds Steam generators and pressure vessels Bearings, shafts, and engine parts On-site testing of permanently assembled components Large-scale metallic workpieces Inventory material identification and failure analysis Specifications Working Voltage 3V(two AA size, alkaline batteries) Power supply Two ordinary AA batterie Measuring range （170～960）HLD Impact direction vertically downward, oblique, horizontal, oblique, vertical upward, automatically identify Error D,±6 HLD Repeatability D,6 HLD Material Steel and cast steel, Cold work tool steel, Stainless steel, Grey cast iron, Nodular cast iron, Cast alu Hardness Scale HL、HB、HRB、HRC、HRA、HV、HS Impact energy D----11mJ Impact weight D----5.5g/7.2g Impact ball hardness D----1600HV Impact ball diameter D----3mm Impact ball material D----Tungsten carbide Sample surface roughness D----1.6μm；C----0.4μm Min depth of harness layer D----≥0.8mm；C----≥0.2mm Display High-contrast Segment LCD Storage 100 measurement series.(Relative to average times 32～1) Calibration Single-point calibration Data printing Thermal printing on site Power consumption Low-power design Standby period About 100h（without backlight） Communication port USB1.1 Working language English Shell material ABS plastic Dimensions 150mm×74mm×32 mm Weight 4.0KG PC software None Downloads PDF Specification Sheet - Download Here
