Servomex was founded in the United Kingdom in 1952 by three partners: Richard Steel, John Crockett and Ronald Mudie. Originally a manufacturer of electronic products including capacitor boxes, waveform generators and a successful range of mains (AC) voltage stabilizers/controllers, Servomex started the journey to today’s business when Richard Steel met Charles Munday, who was developing an advanced version of the paramagnetic oxygen sensor using a platinum feedback loop. Working together, the team manufactured a revolutionary Paramagnetic cell, designed for the accurate and stable measurement of percentage levels of oxygen. This landmark innovation became the basis for a business which has grown over 60 years to become today’s global leader in gas sensing. Our aim is to instill a positive business culture that empowers our staff to engage with our stakeholders in a manner that is honest, transparent and trusted the world over.

Servomex is part of Spectris plc, the productivity-enhancing instrumentation and controls company. Spectris is a leading supplier of productivity-enhancing instrumentation and controls. The Company’s products and technologies help customers to improve product quality and performance, improve core manufacturing processes, reduce downtime and wastage and reduce time to market. Its global customer base spans a diverse range of end user markets. Spectris operates across four business segments which reflect the applications and industries it serves: Materials Analysis, Test and Measurement, In-line Instrumentation and Industrial Controls. Headquartered in Egham, Surrey, United Kingdom, the Company employs approximately 8,300 people, with offices in more than 30 countries.

Since the incorporation of the sensor into the first Paramagnetic analyzer in 1961, Servomex's reputation steadily grew over the next 40 years.  Following the 1999 acquisition of the business by Spectris plc, a leading supplier of instrumentation and controls to global markets, Servomex has been transformed in the 21st century from respected innovator to world leader in gas analysis.

The company's pioneering approach to customer-focused sensing solutions has resulted in a series of landmark innovations, which includes the following world-firsts:

  • The solid electrolyte low-catalytic Zirconia cell
  • The SERVOTOUGH OxyExact process analyzer, unique for use in oxygen-enriched high pressure environments
  • The only true portable Paramagnetic oxygen analyzer
  • A truly accurate Thermal Conductivity sensor
  • The world’s smallest TDL laser monitor

It has established a global presence with the opening of business, service and systems engineering centers based in Shanghai, China; Houston, Texas; Zoetermeer, Netherlands; Mumbai, India; São Paulo, Brazil and Valley Point, Singapore. 

The company's technical and manufacturing edge has been maintained by the opening of a state-of-the-art Technical Center in Crowborough, UK in 2008, as well as acquisition and integration of the Contrôle Analytique and Delta F brands in 2007 and 2010 respectively; the Boston site of the latter is now a counterpart Servomex Technical Center with full manufacturing capability.  Finally, Servomex’s world-leading sensor range has been available under the fast-growing Hummingbird brand, launched to Medical and Industrial OEM customers in 2011.
