Teledyne RDI Citadel CTD-NH RDI Citadel CTD-NH A fast-sampling, fully integrated CTD package for use in environmental monitoring, fisheries, ocean observing networks and other marine applications. It measures condutivity and temperature with depth and utilises the patented Non-eXternal Inductive Cell (NXIC) conductivity sensor. The CTD-NH exhibits a bio-fouling resistant design, and the NXIC internal conductivity cells do not suffer from proximity effects, allowing it to be mounted in any orientation close to other instruments. The CTD-NH offers optional datalogging and external analog sensor input, and can run for 400 hours on its internal 3V battery pack. It is depth rated to 500 m. 2017-10-16 15:31:15.0 SDN:L22::TOOL1163 SDN:L22::TOOL1163 SDN:L22::TOOL1163 1 1 2017-10-16 15:31:15.0 accepted false
