No pump is required. Sampling frequency is user-selectable up to 25Hz and the instrument has three sampling modes: continuous; defined increment of time or pressure; and on request. The unit is externally-powered and provides real time data as it has no internal data logging capabilities. It can support up to 2 optional additional analogue channels or one additional digital channel. The instrument has a maximum depth range of 6000m."@en ; sdo:inDefinedTermSet ; sdo:name "Applied Microsystems Micro CTD"@en ; sdo:termCode "SDN:L22::TOOL0434" .
