®vertical profiling systemsAutomated water quality monitoring and telemetry systemsproviding 24/7 water column profilingand remote data delivery forfreshwater and marine environments

vertical profilingfor continuous monitoringSimultaneously monitor water quality, water velocity, andmeteorological data 24/7 with an automated Vertical Profiling System,the most comprehensive environmental monitoring system available.Why Profile?Source Water MonitoringWater quality assessmentis best conducted througha complete time series thatmonitors physical,chemical, and biologicalparameters.YSI’s automated VerticalProfiler offers furtheradvancements by samplingat different depths, allowingyou to monitor an entirewater column.19-20˚C18-19˚CVariations in temperature,wind, rainfall, salinity, andflow cause changes in thevertical structure of a watercolumn, varying from highlystratified to well-mixed.sonde collects water qualitydata at uniform stepsthroughout the water column17-18˚Cdata are used toidentify which intakeis closest to the bestwater qualityUsers who apply data froma Vertical Profiler will seethe impacts of the physicalenvironment on their waterresources—without frequenttrips to the field.16-17˚C15-16˚C14-15˚CA Vertical Profiler is moorednext to a water intake tower in a drinkingwater reservoir. Profiler data are used tocontinuously assess water quality, allowinga plant manager to select the mostappropriate intake.
