M502.242.2 Ultrasonic Hardness Tester – Motorised tester with colour LCD and Bluetooth

The M502.242.2 ultrasonic hardness tester is a motorised, portable instrument for rapid, precise hardness screening across HRC, HRB, HRA, HBS and HV scales, designed for workshop and field inspection tasks

• Motorised impact for reproducible results
• Colour LCD with memory for 1,000 readings
• RS232 and Bluetooth data output
• Rechargeable 4.2 V / 4800 mAh battery

Reliable hardness assessment for diverse components

The instrument covers a broad measurement range (20–68 HRC / 55–100 HRB / 60–85 HRA / 100–500 HBS / 100–1500 HV), enabling a single device to address many inspection tasks. With an impact force of 5 N, the motorised striker delivers consistent test energy, reducing operator variation and improving repeatability. Conformity with ASTM A1038-2005 and DIN 50159-1-2008 provides a normative basis for acceptance testing and process control, which is particularly relevant for quality departments requiring traceable results and documented procedures.

Efficient data handling and motorised operation for faster workflows

A motorised test sequence removes variability from manual actuation and speeds up inspection cycles. The colour LCD with backlight presents results clearly and stores up to 1,000 measurement records and 20 calibration values, supporting batch traceability and quick review. For data transfer, the tester offers RS232 and Bluetooth outputs, allowing seamless integration with data loggers or local PCs for further analysis. The rechargeable 4.2 V / 4800 mAh battery supports extended field use and removes dependence on disposable cells, improving uptime and site convenience.

Built for portability and consistent field performance

Weighing approximately 2 kg and built with a compact footprint (160 × 80 × 31 mm), the instrument is easy to handle on benches and in confined spaces. The operating range from −10 °C to 50 °C and humidity tolerance of 30–80% make it suitable for typical workshop environments and many field conditions. The tester is supplied with a protective case and practical accessories — including a connection cable and two comparison plates — which simplify transport, storage and first-use setup while protecting the instrument during transit.

Suitable applications and quality control benefits

This motorised ultrasonic tester is suitable for hardness checks on small forged parts, castings, weld spots, stamped components, mould tools, bearings, gear flanks and for assessing the influence of heat treatment. Delivering fast, non-destructive readings across multiple scales, it supports routine in-process control, incoming inspection and maintenance checks. The combination of documented memory, standard conformity and reproducible impact makes the device an efficient tool for production teams who value speed and verifiable results.
