NEREIDES
About
NEREIDES, based in Villejust, France, has been active since 1970 as a specialist in high-value instrumentation and integrated measurement solutions for environmental monitoring. The company operates across four core sectors: water quality, air and gas emissions analysis, meteorology and oceanography, and defense/naval systems — offering end-to-end services spanning study, design, manufacture, integration, operation, and maintenance. In the water domain, NEREIDES produces the OILSPY real-time hydrocarbon detection system for identifying oil and fuel spills in surface water, retention basins, and industrial discharge points, paired with the OILSTOP automated closing valve that isolates detected spills to prevent downstream contamination. Their continuous water quality analysis stations monitor physical-chemical parameters including pH, dissolved oxygen, conductivity, and turbidity across natural environments and industrial sites. For air and gas analysis, NEREIDES distributes the OPSIS DOAS (Differential Optical Absorption Spectroscopy) system for continuous industrial emissions monitoring, SYNSPEC gas chromatographs for volatile organic compound analysis, LSE analyzers for ammonia and nitrous oxide measurement (relevant to wastewater treatment plant emissions), ECOTECH ambient air quality analyzers, and the OLICEM environmental data monitoring platform for aggregating and transmitting distributed sensor network data. Their meteorological and oceanographic divisions supply measurement buoys, weather balloon systems, and the Seaguard scientific measurement platform for multi-parameter marine research. The defense division produces wire antenna systems enabling submarines to receive VLF, LF, HF, LORAN C, and GPS communications while submerged. Marine mechanics products include powered and manual winches, counting pulleys, Shipeck bottom sediment samplers, and water sampling bottles for environmental field operations.
