Deploy this high performance, multiparameter sonde in-situ for weeks, months, or years.

Expand monitoring timelines and collect higher quality data while reducing maintenance costs. This multiparameter sonde with an optional UV based biofouling control is suitable for deployment to 500 m. With UV•Xchange™ preventing fouling-induced drift, the sensors perform to their full potential for the duration of the deployment. Turner Designs Cyclops-7F sensors install directly onto the sondes for seamless integration of two proven solutions. 

This multiparameter sonde has proven to perform long term in-situ.

Take advantage of Xchange™ sensors’ field swappability. This multiparameter sonde can also be suitable for ROV mount. One instrument meets multiple deployment requirements. Ideal for coastal environmental monitoring, aquaculture monitoring, and buoy mounted applications.

This model accommodates five sensors. A copper nickel alloy cage option (shown) is available for incidental biofouling protection.
