YSI ProQuatro
The YSI ProQuatro is the latest handheld multiparameter water quality field instrument from YSI, replacing the ProPlus. Up to four probes can connect to a single cable and up to 12 parameters can be measured. As the latest handheld it is designed to be tough, smart and versatile with IP67 waterproof rating and military spec connectors. A new USB port feature allows users to upload their data directly to a flash drive for easy access whether in the field or the lab.
