The CTD sensors utilise the patented Non-eXternal Inductive Cell (NXIC) conductivity sensor, originally developed by FSI for the US Navy DT-705 Sound Velocity/Salinity sensor. Models in the collection include the NXIC CT Bio Direct Read-500M, NXIC CTD Bio Direct Read-500M, NXIC CTD Bio Auto-500M, NXIC CTD Direct Read-500M, NXIC CTD Direct Read-700M, NXIC CTD Auto-500M, NXIC CTD Auto-700M, NXIC CTD-ADC with external sensors, and the NXIC ETSG Thermosalinograph. Parameters are measured to an accuracy ranging from 0.002-0.010 mS/cm for conductivity, 0.005 degC for temperature and 0.08% for full scale pressure. Now marketed by Teledyne RD Instruments."@en ; sdo:inDefinedTermSet ; sdo:name "Falmouth Scientific Instruments NXIC CTD Series"@en ; sdo:termCode "SDN:L22::TOOL0173" .
