LI-COR LI-200 PyranometerDownload Datasheet
The LI-200 Pyranometer is designed for field measurement of global solar radiation in agricultural, meteorological, and solar energy studies. In clear unobstructed daylight conditions, the LI-COR pyranometer compares favorably with first class thermopile type pyranometers but is priced at a fraction of the cost.
The LI-200 features a silicon photovoltaic detector mounted in a fully cosine-corrected miniature head. Current output, which is directly proportional to solar radiation, is calibrated against an Eppley Precision Spectral Pyranometer (PSP) under natural daylight conditions in units of watts per square meter (w m-2). Under most conditions of natural daylight, the error is < 5%.
