Ultrasonic Hardness Tester M502.242 – motorised, rechargeable and ready for mobile use

The Ultrasonic Hardness Tester M502.242 is a motorised, portable instrument for rapid hardness checks across a broad range of materials, suitable for mobile inspections and on‑bench quality control.

• Motorised probe for stable, repeatable readings
• Colour LCD with backlight and 1,000-value memory
• Wide hardness range across HRC/HRB/HRA/HBS/HV
• Integrated rechargeable battery with USB charging

Fast, reliable hardness checks that keep production moving

The motorised impact mechanism delivers consistent contact force, reducing user variation and enabling repeatable results across small forgings, castings, weld points, bearings and gear flanks. The instrument covers a comprehensive hardness window (20–68 HRC / 55–100 HRB / 60–85 HRA / 100–500 HBS / 100–1500 HV) which makes it suitable for routine shop‑floor verification as well as incoming inspection. Measurements are performed with a defined 10 N impact force, giving a predictable cause‑and‑effect relationship between material response and displayed value. The colour display with backlight stores up to 1,000 readings and 20 calibration settings, allowing batch checks without interrupting workflow.

Built for mobility and straightforward operation

Designed for field and workshop use, the tester is compact and weighs approximately 2 kg, with an operating temperature range from −10 °C to 50 °C and permitted relative humidity of 30–80 %, so it tolerates typical industrial environments. The rechargeable 4.2 V / 4,800 mAh battery supports extended measuring sessions and can be recharged on site; the supply and protective case are included for secure transport and storage. The motorised drive, clear visual feedback and stored calibration values shorten learning curves and reduce cycle time, helping teams maintain production throughput while improving inspection coverage.

Data handling and conformity for quality assurance

Measurement data can be exported via RS232 or Bluetooth, enabling seamless integration into documentation routines or SPC systems. The internal memory retains readings for traceability, and the instrument conforms to recognised reference methods (ASTM A1038‑2005 and DIN 50159‑1‑2008), supporting acceptance in regulated environments. Included accessories such as comparison blocks and the connection cable facilitate verification and quick set‑up. Together, these features support a rational, evidence‑based approach to hardness control and reduce the need for repeat testing.
