For use in high-pressure 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 can either be operated with a generic terminal emulation program such as HyperTerminal or RealTerm, or with a dedicated software such as Logger2150 or LabVIEW. Custom-housed versions of this sensor are also available for gliders and other undersea or monitoring applications. Optional inclusion of temperature in the data stream. The QCP-2150 has a sample rate up to 250 Hz and is designed for operation in waters to depths of up to 6,800 m."@en ; sdo:inDefinedTermSet ; sdo:name "Biospherical Instruments QCP-2150 [underwater] PAR sensor"@en ; sdo:termCode "SDN:L22::TOOL1737" .
