Founded in 1893 by Raphaël Chauvin and René Arnoux, Chauvin Arnoux has had a considerable influence on the development of measurement technology.
A long and prestigious list of inventions, such as the Universal Tester (the precursor of the multimeter) and the ammeter clamp, bears witness to this fact. Throughout the 20th century, Chauvin Arnoux filed more than 350 patents and trade marks.
These last few years have been marked by the gain of some impressive brand names such as Metrix, Pyro-Contrôle, Enerdis, Oritel and Radio Contrôle
The Chauvin Arnoux Group is organized into activity-based divisions around its traditional areas of expertise:
Portable instruments for Test & Measurement of electrical and environmental parameters (CHAUVIN ARNOUX, METRIX & MULTIMETRIX brandnames),
Power Measurement & Control instruments (ENERDIS & RADIO-CONTROLE brandnames) for measurement, metering and supervision of electrical networks,
PYRO-CONTROLE thermosensors and temperature measurement, control and supervision instruments.
