YSI ProDSS Multiparameter Water Quality Meter

Handheld multiparameter instrument with multiple cable options

The YSI ProDSS (digital sampling system) handheld multiparameter meter provides extreme flexibility with two main cable options. Choose between the fully loaded 4-port cable assembly outfitted with any four DSS sensors (with depth or no depth) or the ODO/CT probe and cable - where you get accurate DO measurements every time with an optical dissolved oxygen sensor with an inline conductivity sensor, allowing for real-time salinity compensation.
