Mitech MU220 Ultrasonic Hardness Tester

Mitech MU220 Ultrasonic Hardness Tester

Product Overview

The Mitech MU220 Ultrasonic Hardness Tester is a high-precision, portable instrument based on Ultrasonic Contact Impedance (UCI) technology. Designed for non-destructive testing (NDT), it provides fast and reliable hardness measurement of metallic and alloy materials—including those with complex shapes or delicate surfaces—without causing surface damage.

Ideal for modern production environments, maintenance applications, and laboratory settings, the MU220 offers real-time hardness readings with high accuracy, multi-scale conversion (HV, HRC, HB), and extensive data storage. Its advanced features make it a superior choice for professionals needing mobility, speed, and precision in material hardness evaluation.

Key Features

• Non-destructive hardness testing using UCI (Ultrasonic Contact Impedance) method

• Fast measurement results in less than 1 second for high productivity

• Compatible with flat, curved, and irregular surfaces without causing damage

• Uses a Vickers diamond indenter with ultrasonic vibration for accurate measurement

• 3.5-inch high-resolution color LCD for displaying real-time results and statistics

• Supports multiple hardness scales: Vickers (HV), Rockwell (HRC, HRB, HRA), Brinell (HB)

• Single-point and multi-point calibration ensures accuracy across various materials

• Stores complete test records: time, min/max/avg values, and measurement count

• Bluetooth printing support for optional wireless data output

• Meets international standards: DIN 50159-1:2008, ASTM A1038-2005, JB/T 9377-2010, JJG 654-2013, GB/T34205-2017
