ProQuatro Multiparameter Meter, YSI (CAT#: STEM-AIAE-0062-ZJF)

The ProQuatro Multiparameter Meter manufactured by YSI offers the measurement of a variety of combinations of dissolved oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium (ammonia), nitrate, chloride, and temperature.
Aside from its impact-resistant and waterproof case, the ProQuatro includes features that facilitate field sampling, including user-replaceable cables and sensors, salinity compensation for DO measurements in real-time, a built-in micro USB port for transferring data to a flash drive, and fast response times.
