It provides higher quality salinity data than previous versions of the instrument. It was developed in the 1970s by Neil Brown Instrument Systems, later EG&G, and is no longer in production, but is supported (repair and calibration) by General Oceanics."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0431" ; skos:note "accepted"@en ; skos:prefLabel "Neil Brown MK5 conductivity temperature and depth system"@en ; skos:related . skos:narrower . skos:related . skos:narrower . skos:narrower . skos:narrower .
