Argo Profiling Float CTDs
CTD modules for autonomous profiling floats: the SBE 41/41CP standard Argo CTD and the SBE 61 Deep Argo CTD rated to 7000 m.
Description
The SBE 41/41CP is the standard CTD for Argo profiling floats, developed for highly stable, accurate temperature and salinity. The SBE 61 Deep Argo CTD evolves it for deployments to 7000 m, with improved electronics, dry-gas backfilled conductivity electronics, extended calibration history, pump-controlled TC-ducted flow, a U-shaped flow path and anti-foul protection for multi-year deployments.
