Your specialist for UCI hardness testing technology

From our base in Reutlingen, we produce high-quality measuring equipment for rapid and reliable hardness testing on metallic components and materials.

The UCI hardness testing method has proven its worth for mobile, on-site hardness testing as well as automated mass production. NewSonic offers manual and motorised probes with various test forces from 1N to 98N which work in accordance with the UCI method and can be used for almost all quality assurance and production applications.
In addition to our portable standard products, we also offer special solutions and testing equipment for automated hardness measuring on the production line.

The NewSonic team will be glad to partner with you and assist with any questions you may have concerning hardness testing We would be happy to advise you on location to find the optimal solution for your testing needs.

Final integration of NewSonic into FOERSTER

The time has come: NewSonic will be fully integrated into FOERSTER, both organizationally and spatially, as of August 1st, 2021. This means that the relocation of the delivery and ordering systems as well as the location will be completed.

This current step of integration now has an impact on the commercial documents.

For all commercial transactions we kindly ask you to consider the following:

Purchase orders and service cases

The decisive factor in commercial documentation is the time at which the service is performed, i.e., for example, when an order is delivered to you.

In order to allow a phase of transition, orders that will be delivered from 01 August 2021 can already be accepted by FOERSTER from now on. Please address your business transaction accordingly!

If you already know today that the delivery will only be after August 01, 2021 or if you accept a delivery after August 01 for your order, we would like to ask you to address your order to FOERSTER already today.

Deliveries via NewSonic are still possible until Friday, 23rd July 2021. Due to the move, there will be no deliveries in the week from 26th to 30th July 2021. Thank you very much for your understanding!

In case of service procedures, we recommend that you briefly contact us for processing.


Please make the necessary changes to the new addressing in your systems. The new supplier address is:

Institut Dr. Foerster GmbH & Co. KG
In Laisen 70
72766 Reutlingen

We would like to ask you to send in service work (calibrations, repairs) to the following address:

Institut Dr. Foerster GmbH & Co. KG
Service BU MT
In Laisen 70
72766 Reutlingen

Please include an info with the product name and the request (e.g. SONODUR repair or calibration) to help us to further ensure short turnaround times.


For further communication we would kindly like to ask you to use the following:

Phone: + 49 71 21 140-0

For a transition period, the NewSonic homepage will continue to exist.

Our concern is to make the transition as smooth as possible, knowing that change always brings questions.  Are details still unclear? Then please contact us directly!

We thank you very much for your understanding and support of this 'new beginning'!

Hardness testing devices

Hardness testing is one the most used methods for determining the mechanical properties of materials.It serves as quality control and helps characterise material properties. Since hardness is not a physical dimension, but rather a response to a specific test procedure, there are a range of hardness scales on offer, such as Vickers, Brinell, Shore and Rockwell.

Our portable hardness testing devices use the UCI and Leeb methods, correspond to applicable DIN/ASTM standards, and enable quick and easy hardness measurements on location, even in difficult to reach testing positions.
