Chauvin Arnoux Group
Professional Electrical Measurement InstrumentationOver 100 Years of Innovation
Since its' origins in 1893, Chauvin Arnoux has demonstrated a permanent willingness to be of service to measurement: the measurement of physical quantities with electric or electronic processes.
It is not a question of simply manufacturing measurement instruments but rather of supplying the user with the solutions to their problems throughout the chain of measurement: sensor, meter, display, regulator, convertor, transformer, counter, recorder…
Chauvin Arnoux has thus been very closely involved in the history of the profession of measurement in the 20th & 21st centaury, participating actively in its' development and often anticipating its' evolution as a precursor.
The first instruments were developed with the scientific collaboration of Pierre Curie, D'Arsonval, Georges Claude, Le Chatelier & Nobel Prize in Physics winner (1920) Charles-Edouard Guillaume
Scientific and technical mastery has been achieved with hundreds of patents, several of which are deciding stages for the evolution of science.
Chauvin Arnoux was one of the first to use transistors, then microprocessors in its measurement instruments in the sixties and seventies. More than 350 patents have been registered and today 11% of turnover is consecrated to research and development which itself employs over 100 people.
Chauvin Arnoux has always known how to maintain a strong technical and scientific culture, which has enabled it to actively participate in the creation of measurement in the 20th centaury and which will allow it to continue to play a major part in the innovation of measurement in the 21st century.
