The YSI ProDSS is a high-performance portable multiparameter water quality instrument engineered for comprehensive environmental sampling and field testing. Unlike single-parameter meters, the ProDSS handheld platform lets you connect up to four smart digital sensors simultaneously, measuring parameters such as dissolved oxygen, pH, conductivity, turbidity, algae indicators, salinity, and more. Designed for rugged use in surface water, groundwater, coastal, wastewater, and aquaculture environments, this customizable system provides reliable data with expandable cable options and smart sensor recognition.
