YSI Pro DSS

YSI Pro DSS

The YSI ProDSS (digital sampling system) is a portable water quality multiparameter instrument for the measurement of several critical parameters - dissolved oxygen (optical), total algae, turbidity, pH, ORP, conductivity, specific conductance, salinity, TDS, resistivity, TSS, ammonium, ammonia, chloride, nitrate, depth (optional), temperature and GPS coordinates.

Designed for use in applications such as surface water, groundwater, coastal/estuarine, aquaculture, and wastewater, the rugged and reliable ProDSS allows for the measurement of water quality parameters with digital sensors. The ProDSS water quality meter uses smart sensor technology that allows sensors to be automatically recognized by the handheld while retaining calibration data.
