The SonoDur 3 is the latest generation of portable UCI Hardness Tester from NewSonic. Featuring the Android Operating System, the SonoDur 3 has data transfer and export functions via USB, WLAN or Bluetooth with virtually unlimited storage capacity of measurement data.

Works with a Full Suite of Probes

The SonoDur 3 hardness tester works with both manual probes – standard, long, thin and specialized  (1N to 100N, 0.1 to 10 kgf) or motorized probes (1N to 8.6N, 0.1 to 0.9 kgf) to test the hardness of metals. The long, thin and special versions allow testing of difficult to reach areas. The SonoDur3 UCI (Ultrasonic Contact Impedance) probes work with a variety of different manufactured parts including serial parts after heat treatment, welds, coatings and in applications after surface processing.

For applications involving heat-treated, non-heat-treated, and heavy components, handheld Leeb probes are available during hardness testing. The reference scale for Leeb probes is Vickers HV10, calculated from the L-value per ISO 16859. The SonoDur 3 can be updated with the SonoDur-L app to function with these probes. Leeb probes connect to the SonoDur 3 via Bluetooth.

Replaces MIC10/MIC20 & Conforms to ASTM/DIN

The SonoDur 3 (and SonoDur 2) replaces GE’s MIC 10 and MIC 20 series UCI hardness testers. Using rapid hardness measurements via a Vickers diamond, the SonoDur 3 will help you assess whether or not your parts meet your hardness quality assurance standards. The unit meets ASTM A 1038 and DIN 50159-1 and 2 standards and can convert readings to ASTM E 140-13 and EN ISO 18265 material tables. The Vickers diamond testing pressure displays digitally and refreshes after each measurement.

Intuitive Menus/Touchscreen

The SonoDur3 features an intuitive touchscreen interface and enables reassessments for other hardness scales and adheres to applicable standards for the particular probe in use. The unit also features recognition and test controls with calibration, material reassessment table, time of probe penetration, operator name and tolerance thresholds.

Current Technology

The SonoDur3 is kept up-to-date with free updates made available from NewSonic.

Wide Range of Applications

Wide-range testing ability: The SonoDur3 makes it possible to measure soft aluminum (20HB) to harder metals (approx. 1600HV) using a probe.
