SCIENTIFIC NS \\WHEN MEASUREMENTS MATTER Overview The LI200R, manufactured by LI-COR, is a silicon pyranometer that accurately monitors sun plus sky radiation for solar, agricultural, meteorological, and hydrological applications. It uses a silicon photovoltaic detector mounted Benefits and Features ) Calibrated against an Eppley precision spectral pyranometer (PSP) for the daylight spectrum (400 to 1100 nm) Technical Description The LI200R measures incoming solar radiation with a silicon photovoltaic detector mounted in a cosine-corrected head. The detector outputs current; a shunt resistor in the sensor cable converts the signal from current to voltage, allowing the LI200R to be measured directly by Campbell Scientific data loggers. Specifications Sensor Silicon photovoltaic detector mounted in a cosine-corrected head Measurement Description Measures sun plus sky radiation Spectral Range 400to 1100 nm Calibration +5% traceable to the U.S. National Institute of Standards Technology (NIST) For comprehensive details, visit: www.campbellsci.eu/1i200r-| LI200R Pyranometer Accurate, Versatile Compatible with most Campbell Scientific data loggers in a cosine-corrected head to measure solar radiation. A shunt resistor in the sensor's cable converts the signal from microamps to millivolts, allowing this sensor to be measured directly by a Campbell Scientific data logger. ) Uniform sensitivity up to 82° incident angle ) Cosine-corrected miniature head The LI200R is calibrated against an Eppley Precision Spectral Pyranometer to accurately measure sun plus sky radiation. Campbell Scientific does not recommend using the LI200R under vegetation or artificial lights because it is calibrated for the daylight spectrum (400 to 1100 nm). Sensitivity 0.3 kWm? mV!
