YSI ProDSS Multiparameter Water Quality Meter

YSI ProDSS Multiparameter Water Quality Meter

The YSI ProDSS is a highly versatile portable multiparameter device for water quality measurement. It offers two main cable options: a 4-port set compatible with up to four interchangeable sensors or the ODO/CT probe, which combines an optical dissolved oxygen sensor with a conductivity sensor for real-time salinity compensation. Designed for field use, the ProDSS is ideal for applications in surface, groundwater, and wastewater with a rugged, waterproof (IP-67) housing.

The ProDSS also includes a free online learning platform, ProDSS On-Demand Training, to train users before field operations.

Note: The instrument is sold separately. Cables, sensors, and accessories are not included.

Details:

• Measured Parameters: Dissolved oxygen, turbidity, pH, ORP, conductivity, temperature, salinity, among others.
• Cable Options: 4-port cable or ODO/CT probe.
• Durability: Waterproof housing (IP-67) and military-spec connectors.
• Free Training: ProDSS On-Demand Training.
