EXO2 Multiparameter Sonde


EXO, a state-of-the-art water quality monitoring platform, is designed to address the many challenges of collecting accurate field data in the natural environment. In this video you will learn about the EXO sondes and EXO's innovative features, including: Universal smart sensors; Expansive and high-performance sensor suite; and Extremely rugged design for deeper depths and longer deployments.

The EXO2 is the latest sonde platform offering from YSI.  The EXO2 multiparameter sonde collects data with six user-replaceable sensors, a central wiper to keep sensors clean of biofouling, and an integral pressure transducer for depth.

Smart Ports: Each sensor port on the sonde accepts any EXO water quality sensor and automatically recognises it. Sensors are user-replaceable and made from rugged titanium housing.
