Ultrasonic hardness tester M502.241 — portable tester with 20–68 HRC range and RS232/Bluetooth

The Ultrasonic hardness tester M502.241 is a portable instrument for fast, precise hardness measurement on forgings, castings, bearings and gear flanks, suitable for production control and incoming inspection

• Measurement range 20–68 HRC multi-scale
• Colour LCD with backlight and 1,000-value memory
• RS232 and Bluetooth data output
• Rechargeable battery and robust 2 kg housing

Reliable, standards-compliant hardness readings for quality control

The tester covers a wide set of hardness scales (HRC, HRB, HRA, HBS, HV) with a measurement span of 20–68 HRC / 55–100 HRB / 60–85 HRA / 100–500 HBS / 100–1500 HV, allowing consistent comparison across material types. Resolution/readout values are provided for each scale (for example 0.1 HRC, 1 HV, 1 HB, 1 HLD, 0.1 HS) which supports repeatable pass/fail decisions in production. Compliance with ASTM A1038-2005 and DIN 50159-1-2008 gives a clear technical basis for acceptance criteria and audit trails.

Fast inspection and traceable results to speed throughput

A colour LCD with backlight presents readings clearly in varied lighting conditions, while the built‑in storage for 1,000 measurements and 20 calibration values ensures traceability without immediate PC connection. For process integration the instrument offers RS232 and Bluetooth data output, enabling transfer of measured values into quality control software or handheld loggers. The memory and connectivity reduce paperwork and accelerate batch documentation — a practical efficiency gain for recurring inspections.

Designed for on-site versatility and robust handling

With a nominal impact/measurement force of 20 N the unit achieves consistent coupling energy for ultrasonic contact testing, minimising variability caused by operator pressure. The rechargeable battery (4.2 V / 4,800 mAh) supports extended field use and the compact housing at 2 kg simplifies handling on benches and at machine centres. Rated operating conditions are −10 °C to 50 °C and 30–80% relative humidity, so the instrument remains suitable for typical workshop and site environments. Supplied accessories include a connection cable, two comparison blocks and a protective case for transport.

Practical applications and material suitability explained

The instrument is intended for rapid checks on small forged components, cast parts, weld spots, stamped pieces, tooling, bearings and gear flanks, and for assessing the effect of heat or local hardening. The multi-scale conversion means the same reading can be reported in the hardness scale required by the drawing or standard. For less experienced technicians the numeric readout and saved calibration entries simplify interpretation, while for quality engineers the stored data and standards compliance support documented acceptance.
