Mitech MU220 Ultrasonic Hardness Tester

Mitech MU220 Ultrasonic Hardness Tester

High-Precision Non-Destructive Hardness Testing Using UCI Technology

Brand: Mitech

Model: MU220

Product Overview

The Mitech MU220 Ultrasonic Hardness Tester is a high-precision, non-destructive testing instrument based on the Ultrasonic Contact Impedance (UCI) method, enabling rapid and accurate hardness measurement of a wide range of metal materials, including modern composites and new alloys. Unlike traditional methods, MU220 applies minimal pressure and causes no surface damage, making it ideal for components with strict surface integrity requirements.

Equipped with a 3.5-inch color LCD screen, advanced calibration options, and conversion between multiple hardness scales (HV, HB, HRC), the MU220 offers intuitive operation, high reliability, and versatility across diverse testing scenarios. It is particularly suitable for industrial environments where both accuracy and portability are essential.

Key Features

• Non-Destructive Ultrasonic Testing (UCI Method)
  Utilizes ultrasonic resonance with a standard Vickers diamond indenter, ensuring minimal surface damage while delivering direct Vickers hardness readings.

• Fast and Accurate Measurements
  Provides results in less than 1 second, suitable for high-throughput environments and field use.

• High-Resolution Display
  3.5-inch color LCD screen shows real-time hardness values, test statistics, material type, and conversion standards in a clear and user-friendly format.

• Single-Point and Multi-Point Calibration Modes
  Improves accuracy across different materials, including composites, new materials, and parts without standard hardness conversion tables.

• Comprehensive Hardness Conversion
  Supports direct conversion between Vickers (HV), Rockwell (HRC, HRB, HRA), and Brinell (HB) hardness systems.

• Data Storage and Output
  Automatic storage of measurement data including test time, maximum/minimum/average values, and total measurement count. Compatible with optional Bluetooth printer for real-time data output.

• Flexible Material Testing
  Easily adaptable to different materials without changing the probe—just use calibration blocks with similar properties.

• Standard-Compliant
  Conforms to international and national hardness testing standards:
  DIN 50159-1-2008, ASTM-A1038-2005, JB/T 9377-2010, JJG-654-2013, GB/T34205-2017.

Applications

The Mitech MU220 is ideally suited for a variety of industrial and field applications, including:

• Hardness testing of complex parts such as flanges, gear roots, stamped components, and thin plates

• Face-hardened surfaces, gear grooves, tapers, and small radius features

• Rotating parts like wheels, turbine rotors, axles, and bit edges

• Thin-walled pipes and vessels

• Weld seams and heat-affected zones

• Hardness depth analysis in concave/convex surfaces and deep holes with small apertures

• General testing of ferrous and non-ferrous metals, including their alloys, in manufacturing and quality control
