Measuring conductivity, temperature and depth is central to understanding the water column, tracking upwelling and currents, calculating water density and looking at biochemical processes above and below thermoclines and haloclines.

Our rugged CTD loggers provide an all-in-one platform for easy profiling and feature durable construction for cost-effective, long-term monitoring. Expand on your CTD platform with multiparameter instruments in five- and seven-port configurations, featuring interchangeable, fast-response sensors, easy field calibration and an optional wiper to fight biofouling and extend intervals between maintenance visits.

All instrumentation, cables, telemetry and software work together for ease of use and flexibility. View your data instantly with the VuSitu mobile app’s Graphing Assistant or deploy instrumentation long term with VuLink telemetry for real-time data from a dock or moored buoy.
