MU220 Ultrasonic Hardness Tester

Product catalog summary

Overview: The MITECH MU220 is a non-destructive ultrasonic hardness tester utilizing the Ultrasonic Contact Impedance (UCI) method. It is designed for quick and accurate hardness testing of various metal materials, including composites and new materials, without damaging the surface. The device features a 3.5-inch LCD color display and supports conversions among different hardness systems.

Technical Specifications: The tester adheres to standards such as DIN50159-1-2008 and ASTM-A1038-2005. It covers a hardness range of HV50-1599, HRC20-76, and HB76-618, with a test error margin of ±2HRC for HRC and ±3% for HB and HV. The device operates within a temperature range of -20℃ to 50℃ and a humidity level of ≤85%.

Features: The UCI method, developed by Dr. Claus Kleesattel, uses a resonating rod with a diamond indenter to measure hardness. The device offers fast measurement speeds, with results available in one second, and includes a built-in conversion function for Brinell, Rockwell, and Vickers hardness systems. It supports both single-point and multi-point calibration modes for enhanced accuracy.

Applications: The MU220 is suitable for testing the hardness of flange edges, gear roots, molds, thin plates, axles, thin-wall pipes, wheels, turbine rotors, welding parts, and various ferrous and nonferrous metals in industrial production.

Configurations: The standard configuration includes a main unit, manual probe, probe cable, power charger, USB cable, standard hardness block, and an ABS case. Optional accessories include a Bluetooth printer and various probe test forces ranging from 0.5kgf to 10kgf.
