M502.240 Ultrasonic Hardness Tester — Portable, Standards‑Compliant Device (Metav IndustryLine)

The M502.240 Ultrasonic Hardness Tester is a portable instrument for fast and precise mobile hardness checks on forged components, cast parts, weld spots, stamped pieces and rolling elements.

• Portable design with rechargeable battery
• Conforms to ASTM A1038 and DIN 50159-1
• Wide hardness range across HRC/HRB/HRA/HV/HBS
• RS232 and Bluetooth with 1,000-value memory

Rapid, standards-based hardness measurement for production control

The instrument uses the ultrasonic method to determine material hardness quickly without destructive testing, producing immediate values across the commonly required scales. Thanks to its certified conformity with ASTM A1038 and DIN 50159-1, results can be integrated into quality workflows and documentation. The listed hardness range covers HRC, HRB, HRA, HV and HBS, allowing a single device to replace multiple test methods and reduce setup time during incoming inspection or process checks.

Designed for mobile inspection and workshop durability

A compact construction and a rechargeable battery (4.2 V / 4,800 mAh) make the unit suitable for on‑site use and extended inspection rounds; the device weighs approximately 1 kg and runs in ambient conditions from −10 °C to 50 °C with 30–80% relative humidity. The colour LCD with backlight provides clear readouts in dim working environments, while the handheld form factor supports rapid placement on stepped surfaces and small mouldings. This practicality reduces downtime and speeds sampling across maintenance and production tasks.

Secure data handling and traceability for quality assurance

Data connectivity is available via RS232 and Bluetooth, with internal storage for 1,000 measurements and up to 20 calibration entries. This facilitates traceable record keeping and straightforward transfer to inspection software or databases for trend analysis. Readout resolutions supplied (e.g., 0.1 HR, 1 HV, 1 HB, 1 HLD, 0.1 HS) meet industry expectations for workshop control, enabling consistent reporting without manual transcription.

Practical applications and operational benefits in manufacturing

The device is intended for the measurement of small forged parts, castings, weld spots, stamped elements, die cast tools, bearings and gear flanks, and for assessing the influence of heat treatment or thermal exposure. By consolidating multiple hardness scales in a single instrument and offering rapid single‑point results, the tester supports faster decision making on rework, acceptance or further processing. The combination of portability, standards compliance and dependable data output reduces inspection complexity and supports continuous production quality.

FAQ

How does the ultrasonic method determine hardness and which scales are available?
The ultrasonic impulse method measures the material response to a defined impact; the M502.240 converts this response into hardness values across HRC, HRB, HRA, HV and HBS scales for broad applicability.

Can measurement data be exported to a computer or quality management system?
Yes, the unit offers RS232 and Bluetooth connections and stores up to 1,000 measurements plus 20 calibration sets for straightforward data transfer and archiving.

Is the device suitable for use on heat‑treated components and welds?
The tester is expressly suitable for assessing the effect of heat or thermal cycles on parts; typical applications include weld spots, forged parts and tools where hardness variation is a concern.
