Model 503 CTD
NBOSI’s Model 503 CTD provides research-quality CTD (conductivity, temperature and depth) data in real time, as well as salinity, speed of sound and density. The rugged unit is fully potted and features a low-profile two-piece cylindrical design that allows it to be installed within a flooded hull segment, with a shroud that can be modified to match a range of hull diameters. Data can be output at up to 10 Hz via standard serial RS-232.
The Model 503's cable can be provided with a user-defined connector, one of a range of bulkhead connector options, or a custom through-hull penetrator specifically engineered for your particular application.
