I want to integrate a moored CTD with some auxiliary sensors (transmissometer, fluorometer, etc.). Which CTD should I use?
Sea-Bird currently manufactures only 1 moored CTD that can accept auxiliary sensors, the SBE 16plus V2 SEACAT (and its inductive modem version, the 16plus-IM V2). These instruments measure conductivity and temperature; a pressure sensor is optional. They have 6 differential A/D channels and 1 RS-232 channel available for auxiliary sensors. Notes: • The SBE 19plus V2 SEACAT, intended primarily for profiling applications, can also be used in moored mode. The 19plus V2 has 6 differential A/D channels and 1 RS-232 channel available for auxiliary sensors. When in moored mode, it functions similar to a 16plus V2 with optional pressure sensor. • The older versions of these products, the SBE 16 / 16plus and SBE 19 / 19plus, also accept auxiliary sensors. See Products at a Glance for a table summarizing the features of our moored instruments.
