Definition	This instrument, also known as the Plessey 9040, incorporates pressure, temperature and conductivity sensors whose output may be digitally logged in addition to the derived parameters depth, salinity and sound velocity. An optional dissolved oxygen sensor is available. Salinity accuracy is quoted at +/-0.02 ppt and temperature accuracy is quoted at +/-0.02 C in normal oceanographic conditions.
