EXO3 Multiparameter Sonde

Multiparameter Water Quality Sonde with 5 sensor ports (including a central wiper port), optional depth sensor, and battery compartment

EXO Multiparameter Sondes — the best-in-class platform for the highest quality data. EXO’s dynamic range of smart sensors provide comprehensive multiparameter water quality data while SmartQC ensures proper calibrations and top sensor performance. You can be confident in your extended deployments thanks to EXO’s tough materials and unmatched anti-fouling technology.

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

The parameters you need, without the features you don’t!


Offering the greatest value of any sonde available on the market, EXO3 combines the maneuverability of the EXO1 with the powerful antifouling wiper of the EXO2.

The EXO advanced water quality monitoring platform includes the versatile multiparameter EXO3 sonde, which is suitable for oceanographic, estuarine, or surface water applications.

EXO3 is a purpose-built sonde for monitoring major water quality parameters, including pH, conductivity, temperature, turbidity, and dissolved oxygen.
