EFS SAS
About
EFS SAS is a French instrumentation manufacturer based in Montagny, near Lyon, with over 40 years of multidisciplinary expertise spanning electronics, optics, IT, and mechanics. The company designs and produces online water quality analysis equipment for continuous monitoring of drinking water, surface water, and industrial effluent. Their flagship I-CENSE probe installs directly into pressurized drinking water pipes via hot tap without bypass, operating autonomously for over one year on battery with 4G-NBIoT connectivity. It measures free chlorine (ISO 7393 colorimetric microfluidic method, 0-5 mg/L), turbidity (ISO 7027 nephelometric, 0-50 NTU), conductivity (4-pole electrode, 0-2000 uS), temperature, flow, and pressure with threshold alarm management. The UV-Probe 254+ provides online UV spectrophotometric measurement of COD, BOD, TOC, and organic load indicators for industrial and municipal wastewater. The Turbi-Probe 4000+ is a portable and fixed-installation turbidimeter for highly contaminated water and suspended solids monitoring. EFS also delivers turnkey IIoT effluent monitoring stations that automatically measure flow, levels, COD, BOD, TOC, SS, pH, temperature, conductivity, redox, dissolved oxygen, color, and turbidity. Trusted by SAUR, SUEZ, CEA, and Agur, EFS is a member of the AXELERA and HYDREOS competitiveness clusters.
