For use in underwater applications with a 16 bit or higher analog-to-digital converter. Measures light available for photosynthesis on a flat surface. Operation is by a linear 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 (high-pressure standard option) or 10,000 m (high-pressure user-specific option)."@en . . . .
