Model 501 CTD

NBOSI’s Model 501 sensor provides research-quality CTD (conductivity, temperature and depth) data in real time, as well as salinity, speed of sound and density. Data can be output at up to 10 Hz via standard serial RS-232.

Housed in a compact and rugged enclosure and fully potted, it can be easily integrated into a wide range of platforms, including AUVs, ROVs and USVs, via a number of modular bulkhead connector options. NBOSI can also provide the Model 501 with a custom through-hull penetrator specifically engineered for your particular application.
