Our History

RM&C’s heritage can be traced back to a rather famous individual, Harry Brearley, the inventor of stainless steel who was born in Sheffield in 1871.

In 1908, Harry Brearley founded the Amalgams Company, known today as Roxspur Measurement & Control. RM&C - now part of TT electronics - is a British company, whose success is built on over a century of precision craftsmanship and serving the global industrial manufacturing community. For over 100 years, it has successfully designed, manufactured and applied measurement technologies and services to improve the performance and safety of its customers’ industrial processes.
