YSI ProDSS Multiparameter Water Quality Meter

ProDSS Digital System: Explore, Measure & Trust Your Water Quality Data

Scientific precision in your hands: measure multiple water parameters in the field and lab

The YSI ProDSS (Digital Sampling System) Multiparameter Handheld is a portable water sampling instrument that combines ruggedness, flexibility, and accuracy. Designed for scientific, environmental, and regulatory applications, it allows you to connect up to four smart sensors simultaneously, providing reliable data in surface water, groundwater, coastal water, aquaculture, laboratories, and wastewater. Its advanced digital technology automatically recognizes sensors and retains calibration, saving time and ensuring reproducible results. Available in two versions: with integrated GPS (to record field coordinates) or without GPS.
