Campbell Sci – LI200R-L

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 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.
