2 - Power Measurement & Control instruments (ENERDIS & RADIO-CONTROLE brandnames) for control, metering and monitoring of electrical networks,

3 - Thermosensors and Temperature Measurement & Control instruments PYRO-CONTROLE instruments for measurement, control and supervision.

4 - Finally the MANUMESUREService division offers an extensive range of services for professionals and manufacturers, including after-sales service for the group's products, repair, metrological testing and calibration for electronic devices.

Our Quality Contract, which aims to develop reliable and safe products, is attested by the ISO 9001:2000 certification.

International presence

Chauvin Arnoux has been building its own world-wide sales network for more than 30 years. Eight subsidiaries in Europe, China, and the United States, as well as 150 independent agents and 3,000 sales outlets support its international development. In France, Chauvin Arnoux strengthens its local presence through professional distribution.

Robust design

As far as product development is concerned, a considerable effort allows the company to maintain its position among the best and to propose numerous innovations each year. Respect for standards, metrological rigor, ergonomics, monitoring technological developments and marketing are key words for our experts within the different divisions. The constraints with which developments are carried out are a guarantee of the quality of the products, made to last and safely.

In-house manufacture

Designed in laboratories in France, Austria or in the USA, the products are then manufactured in the Industry division's factories. Plastic and metal mechanical parts are produced in Vire (France), while printed circuit boards are cut in Villedieu (France). Product assembly and testing is then carried out in factories in Europe and the United States.
Also in Vire are manufactured the SMBO shunts.
