Description

Now further developed with a new optimised shape and removable ProLogger module that combines a rechargeable lithium-ion battery, data logger, GPS receiver and Bluetooth comms. The rapidPro CTDplus gives access to many optical sensor parameters based on the Hyperion range and CTD. Optionally, the rapidPro CTD is designed to operate with the Teledyne OceanScience rapidCAST underway profiling winch to deliver the highest quality CTD, and optional optical parameter casts on the move. While the vessel is underway, profiles of up to 450m at 6 knots are expected.
