ECONOX is located in the Swiss Jura, 10 km from the French border. It was founded in 1984. The adventure started in 1986 with the filing of the patent for the first ball-in-tube oxygen sensor. From the start, ECONOX has developed and manufactured equipment intended for measuring and regulating heat treatment atmospheres. Since then, numerous developments have been made in order to satisfy an ever growing and discerning demand. This is how the “CarboProbe” range of oxygen sensors was born. Research was done to meet the stringent requirements of the ceramics industry, research laboratories, potters as well as universities.
