The SonoDur 3 – A Versatile Hardness Testing Instrument

Newsonic’s SonoDur 3 allows inspection on a multitude of different surface geometries and surface conditions. This equipment is designed for portable and immediate hardness testing in research labs, quality inspections, production facilities and in the field. The latest innovation from NewSonic is based on a user-friendly Android system that enables modern data transfer technologies like Bluetooth, WLAN and USB with unlimited storage capacity.

Bluetooth and WLAN enable the user unparalleled data handling capabilities of single measurements or of completed datasets. Intelligent data management allows simple access and back traceability of the results. The data can also be exported in a txt delimited format for cross-platform data transfer.

Internationally Recognized UCI Hardness Technology

NewSonic and the SonoDur series hardness testers are internationally recognized for portable UCI hardness testing. The SonoDur 3 Ultrasonic Impedance Technology is based on a diamond that is resting at the end of a vibrating rod that is depressed on a surface under a fixed load.  The Ultrasonic vibration frequency is then converted to a hardness value. The UCI has several advantages. It is portable, easy and accurate. It is not restricted to large mass items and can measure light and thin walled samples. The Sonodur 3 can also acquire hardness in large parts as well.

Lightweight & Portable

The lightweight and portable design of the SonoDur 3 allows seamless integration with a multitude of available stands and probes to tackle even the most challenging parts and locations. It also provides inspectors instant access to data via its wireless interface. No longer do you need to connect cables to transfer data. The advanced communication features allow you to work with greater efficiency, resulting in time and cost savings.

An Improved Version of the MIC 10/MIC 20

SonoDur 3 is a natural replacement for the now discontinued MIC 10/MIC 20 UCI hardness testers.  The MIC 10 and MIC 20 found their places in the industry featuring high portability and ease of measurement. Inspectors could use these light instruments in the field, working on pipes, scaffolds or for testing components in remote field locations. The wide range of available narrow probes allowed measurements to be taking on areas difficult to reach such as tooth flanks or root of gears.

The Most Complete UCI Hardness Testing Solution

The SonoDur 3 comes to fill the gap after the discontinuation of MIC 10/MIC 20. The SonoDur 3 works with a suite of 18 different probes with test forces ranging from 1N-98N, making it the most universal UCI hardness testing solution available. The new system makes the transition seamless with an intuitive interface and touchscreen as well as with the latest available technologies in OS, statistical data management, and wireless data transfer.

According to Stephen Berg, CEO of Berg Engineering, “Simply put, with the launch of the SonoDur 3, NewSonic took the best, reliable UCI hardness testers in the MIC 10 and MIC 20 and made them better.”

NewSonic also makes probes and cables that can still be used with the MIC 10 in case you still want to use that equipment for its useful life. However, if you make the switch to the SonoDur 3, users will find the transition to be seamless. The intuitive interface and the familiar probes will guarantee that the learning curve for the transitioning user will be smooth.

SonoDur 3 Probes

A full suite of probes is readily available. SonoDur 3 works with both manual and motorized probes. The appropriate probe enables the user to provide reliable and accurate hardness measurements depending on his application.

NewSonic Standard Handheld Probe SONO-50H, 49N/5 kgf.

NewSonic Standard Handheld Probe SONO-50H, 49N/5 kgf.

Standard probes. The standard handheld probes have a range of 10N-98N and can measure hardness on metal, industrial ceramic and depending on the specifics highly heterogeneous materials, such as cast iron. Newsonic’s standard handheld probes are interchangeable with SonoDur2 as well as SonoDur-R ‘Rack’.
