In 1893 Raphael CHAUVIN and René ARNOUX joined together to found CHAUVIN ARNOUX. 120 years later, the adventure continues and the firm is now the parent company of the CHAUVIN ARNOUX Group, specialized in the measurement of electrical and physical quantities. Electricity is a crucial type of energy at the heart of our daily lives. It has to be deployed and distributed while guaranteeing user safety and its consumption has to be controlled with regard to costs and environmental concerns. Deigning, manufacturing and commercializing measuring instruments has been our core business for more than a century, allowing professionals to check and test the reliability, safety and efficiency of electrical distribution systems and the equipment connected to them, on a daily basis. Proud of our two brands, CHAUVIN ARNOUX® and Metrix®, we propose a wide range of measuring instruments used by millions of professionals every day, all over the world. Our offering covers the fields of general electrical measurement (testers, multimeters and current clamps), electrical safety testers, wattmeters and electrical network quality analysers, oscilloscopes and, more generally, instruments for testing electronic devices and measurement of physical parameters.
