General Description
The SBE 52-MP is a conductivity, temperature, depth (pressure) sensor (CTD), designed for moored profiling application in which the instrument makes vertical profile measurements from a device that travels vertically beneath a buoy, or from a buoyant sub-surface sensor package that is winched up and down from a bottom-mounted platform. The 52-MP incorporates pump-controlled, TC-ducted flow to minimize salinity spiking. On typically slow-moving packages (e.g., 20 - 50 cm/sec), its sampling rate of once per second provides good spatial resolution of oceanographic structures and gradients. The 52-MP can optionally be configured with a Dissolved Oxygen sensor module (SBE 43F), as shown in the photo. The SBE 43F is a frequency-output version of our SBE 43 Dissolved Oxygen Sensor, and carries the same performance specifications. The 52-MP is intended for use in marine or fresh-water environments at depths up to 7000 meters (22,900 feet).
