proRheo – your specialist for all questions concerning viscosity

As a manufacturer of rheometers for laboratory and process, we deliver our devices, made in Germany, all over the world. Our strength is our high professional competence and our well-developed dealer and service network worldwide.

Quality guarantee: handmade products from the Black Forest

Since the company was founded in 1994, we have been designing and building viscometers here in the Black Forest and are specialists for all questions concerning viscosity in industry and science.

More than 5000 process & laboratory rheometers from proRheo work reliably in 36 countries and we have made it our business not only to supply our customers with high quality and durable viscometers, but also to support them with our many years of experience and personal service.

We are a traditional company with roots deep in the beginnings of rheology and we share this know-how with our customers and also support them with small problems and difficulties.

We source all of our parts from the region and place a very high value on manufacturing equipment that is not only highly precise, but also robust and of high quality workmanship.

So the words Made in Germany still applies to every step of our work process and we are very proud of that.

Continuity plays an important role in our company. The company headquarters in the northern Black Forest is known for its long tradition of precision mechanical workshops. Of these, selected companies are our long-standing suppliers. Likewise, continuity in our team is an essential aspect. proRheo sticks to the tried and tested: Each newly developed product is based on the experience with the predecessor products and incorporates their capabilities.
