YSI ProDSS Sensors

YSI ProDSS smart sensors give your multiparameter meter the flexibility to measure a wide range of key water quality parameters. These digital smart sensors are automatically recognized by the ProDSS handheld and store their calibration data internally, making setup faster and reducing field downtime.
