Product Information

Main application areas are inspection tasks on serial parts after heat treatment, after surface processing, weld inspection or for coat hardness measuring on gravure cylinders with highly selective low load motorized probes.

The SonoDur2 is the successor to the tried and tested UCI hardness measurement device, SonoDur. It is especially suited to rapid hardness measuring in the fields of production and quality assurance.

EN ISO 18265 material tables have already be stored on the device.

The testing pressure of the Vickers diamonds is digitally displayed and refreshed.

The device has an intuitive menu system enabling reassessments for other hardness scales and in line with other applicable standards or the particular probe in use; it also features recognition and test controls with calibration, material reassessment table, time of probe penetration, operator name and tolerance thresholds.
It is always kept up-to-date thanks to free updates.

Varied uses

The SonoDur2 makes it possible to measure soft aluminium (20HB) through to harder metals (approx. 1600HV) using a probe.

Usable probes

The device is suitable for the operation of manual and motorised measurement probes with test forces between 1N and 100N, as well as long probes for testing applications at measurement positions that are difficult to reach.

Integrated memory

4GB of memory (can be expanded to 32GB) offers enough storage space for an almost limitless number of measured values. The ease by which data can be transmitted via USB makes documentation much easier. Wi-Fi and Bluetooth connections are also possible.

Product features:

  • Standardised, robust, easy, fast and precise German engineering
  • Quick and precise on-site measurements
  • Standardised in accordance with ASTM A 1038 and DIN 50159-1-2
  • High contrast, colour touch screen with alternating colouration of measured values in the event of an alarm – all the essential information at one glance
  • Automatic reassessment into HB, HK, HRA, HRB, HRC, HRF, HRD, HR45, HS, HK, MPa in accordance with EN ISO 18265 and ASTM E 140
  • Signal is processed in the measurement probe, probe connection cable is extendable
  • Digital transmission of the hardness value via USB, enabling simple integration into automatic testing systems
  • Alignment data and measurement series can be saved and retrieved for later use.

Areas of application:

  • Rapid hardness testing on serial parts following heat treatment
  • Hardness testing on parts following surface processing
  • Mobile weld seam inspection in tight spaces
  • Measuring coating hardness with several measurement points
  • Suitable for simple alignment on (almost) all fine-grained, homogenous materials
