Product Description

Smart•X is ideal for AUV or ROV work having been designed with real-time instrument designed with vehicle integration in mind. Take full advantage of Xchange™ sensors with Smart•X: your SVPT can become a CTD and shallow pressure sensors can be swapped for deep as needed. A single real-time instrument meets multiple deployment requirements.

Smart•X is ideal for long term, in-situ deployments with UV•Xchange for biofouling control. By eliminating biofouling-induced drift, UV•Xchange allows sensors to perform to their full potential on in-situ instruments. Install UV•Xchange on a Smart•X for a high performance in-situ CTD.
