Who Are Prosig?

Prosig provides data capture hardware and analysis software and services across a range of applications and industries. Our focus is noise & vibration measurement for the automotive, aerospace, power generation, advanced engineering, defence, industrial & manufacturing industries.

Prosig was established in 1977 by staff from 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.

In 2014 Prosig became part of the Condition Monitoring Group (CMG). Following the addition of Semia and DJB and the arrival of a new CEO, the group rebranded in 2022 to Condition Monitoring Technology Group (CMTG).

Prosig operates through the CMTG facilities in Europe and North America and maintains a network of partners to support business throughout the rest of the world.

The company vision 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.
