For use in underwater applications with 24 bit ADC systems. Measures light available for photosynthesis on a flat surface. Operation is by a single channel compressed analog output voltage that is proportional to the log of incident PAR (400-700 nm) irradiance. The sensor is designed for operation in waters to depths of up to 2,000 m (standard) or 6,800 m (optional)."@en ; sdo:inDefinedTermSet ; sdo:name "Biospherical Instruments QCP-2350 [underwater] PAR sensor"@en ; sdo:termCode "SDN:L22::TOOL1186" .
