Founded in 1992, Rhosonics develops ultrasonic measuring instruments for process optimisation.

From our headquarters in Putten, the Netherlands, we design, produce and supply sensors and analysers for demanding industrial applications. Our technology supports industries including mineral processing, dredging and semiconductor manufacturing.

For more than three decades, Rhosonics has specialised in concentration and density measurement. Since 2009, we have also become a major provider of non-nuclear slurry density measurement technology, helping operations replace radiation-based devices with a safer ultrasonic alternative.

Real-time process data helps operators optimise safely, reliably and cost-effectively. Our role is to make that insight available through practical ultrasonic technology.

MISSION

VISION

01

We believe in teamwork: down-to-earth, transparent and committed to sustainable, long-term relationships with customers and partners.

02

We combine specialist knowledge, leadership and versatility to deliver high-quality measurement technology for real process needs.

03

We take initiative. A practical, creative and adaptable mindset helps us respond quickly and solve problems without unnecessary complexity.

04

We approach challenges with energy and curiosity. That drive helps us keep improving and build lasting growth together with customers and partners.

05

We develop reliable measurement technologies that help customers optimise production, improve efficiency and move towards more sustainable processes.

Research and development have been part of Rhosonics from the beginning. Our instruments measure slurry density, chemical concentration and chemical density in real time, supporting some of the most critical process applications.

Our technology can be found on dredging vessels, throughout mineral processing plants and in advanced electronics and semiconductor production.
