Professional Plus Series

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 (phycocyanin & phycoerythrin), turbidity, pH, ORP, conductivity, specific conductance, salinity, TDS, resistivity, TSS, ammonium, ammonia, chloride, nitrate, depth (optional), temperature and GPS coordinates. the rugged and reliable ProDSS allows for the measurement of water quality parameters with digital sensors. The ProDSS uses smart sensor technology that allows sensors to be automatically recognized by the handheld while retaining calibration data. Some sensors are EPA approved for drinking water and wastewater compliance reporting.
