Handheld Multiparameter Instrument with Digital Sensors

The YSI ProDSS (digital sampling system) handheld multiparameter meter provides extreme flexibility for the measurement of a variety of combinations for dissolved oxygen, turbidity, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium (ammonia), nitrate, chloride and temperature along with depth.

Some sensors are EPA approved for drinking water and wastewater compliance reporting.

Instrument Only.  Cables, probes/sensors, and accessories sold separately.
