The YSI 6600-EDS and 6600
Both the DATAFLOW System and the Continuous Monitoring Stations utilize the YSI 6600 Multiparameter Data Sonde. The sensors include a Clark-type YSI 6562 DO probe, a YSI 6560 conductivity/temperature probe, a 6561 pH probe, a 6136 turbidity probe, and a 6025 chlorophyll probe.
The fixed stations utilize the YSI 6600 equipped with the Clean Sweep Extended Deployment System (EDS) which is comprised of a brush that at set intervals sweeps across the sensors to dislodge any fouling organisms or material that has settled on the sensors. This feature ensures better quality data over longer deployment periods in areas with high fouling rates.
