The sensor can be used for ocean acidification, research coral reef sensitivity analysis and environmental monitoring. The sensor measures pH with a range of 6.5 to 9.0. The sensing element is an ion sensitive field effect transistor. V2 implements improvements to the original SeaFET's reliability, data quality, ease of operation, and deployment endurance, with significant changes to how users interface with the instrument. The pH sensor has an accuracy to +/-0.05 pH, precision of 0.004 pH and stability of 0.003 pH/month. It can operate in temperatures ranging from 0 deg C to 50 deg C and up to depths of 50 m."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1293" ; skos:note "accepted"@en ; skos:prefLabel "Satlantic SeaFET V2 {Sea-Bird Scientific} (shallow) pH sensor"@en ; skos:related .
