Prosig was established in 1977 by members of ISVR (Institute of Sound & Vibration Research) at Southampton University. The company’s goal was to provide customers with the best available hardware and software for noise and vibration measurement.

The existing UK headquarters, in Fareham UK, were completed in 1982 and Prosig USA, Inc. was founded in 1986. In 2001 an engineering center was opened in Detroit to provide high quality support to customers in the area. Prosig’s US operations are now run from CMTG’s facility in Elk Grove Village, Illinois.

In 2014 Prosig became part of Condition Monitoring Group (CMG). The combination of Prosig’s expertise & heritage and the technologies & knowledge in CMG has led to significant benefits to our customers. Following the addition of Semia (2020) and DJB (2021) to the group and the arrival of a new CEO the group was rebranded as Condition Monitoring Technology Group (CMTG) in 2022.

CMTG has sales & support offices in the USA, France, Italy & Germany and Prosig maintains a network of partners to support business worldwide.

The company vison has always been focused on producing reliable, high quality, integrated measurement solutions that allow our customers to achieve best practice by using the latest tools available to the test engineer.
