A deuterium lamp provides a light source of 1 cm path length; the measured spectrum falls within the Ultraviolet (UV) 190 nm - 370 nm wavelength range. Measurement accuracy: +/- 2 umol/l or 10 %; detection range: 0.5 umol/l to 2000 umol/l. The instrument is based on the MBARI-ISUS technology; it was originally developed and manufactured at Satlantic, and was rebranded as a Sea-Bird Scientific product following the company's acquisition by Danaher in 2011."@en ; skos:notation "SDN:R27::SUNA" ; skos:note "accepted"@en ; skos:prefLabel "Submersible Ultraviolet Nitrate Analyser (SUNA) nitrate sensor"@en .
