| Definition | An underwater CTD probe designed for on-line profiling or used in self-recording applications such as on moorings or AUVs. It comprises a piezoresistive pressure transducer, a platinum resistance thermometer, a platinum seven-ring quartz conductivity cell, a pressure-compensated polarographic oxygen sensor, a pH glass sensor and solid gel pH reference probe. The conductivity cell employs a large diameter (8 mm) and a short length (46 mm) which facilitates self-flushing and prevents clogging. The conductivity cell design does not require platinum black deposition and can be cleaned in the field without re-calibrating. The probe can accommodate up to 16 auxiliary sensors. The probe can be interfaced with a telemetry deck unit for real-time data acquisitions. It is depth rated to 7000 dbar. Pressure accuracy: 0.01 - 0.05 % FS. Temperature accuracy: 0.002 deg C. Conductivity accuracy: 0.003 mS/cm. | |
