The 200SZ Silicon Pyranometer is designed for solar radiation measurement in agricultural, meteorological, and solar energy studies. In clear unobstructed daylight conditions, the 200SZ Silicon Pyranometer compares favorably with first class thermopile type pyranometers, but at a fraction of the cost. It features a silicon photovoltaic detector mounted in a fully cosine-corrected miniature head. Current output, which is directly proportional to solar radiation, is calibrated under natural daylight conditions in units of watts per square meter (Wm). Under most conditions of natural daylight, the solar radiation measurement error is less than 5%. Because the spectral response of the 200SZ Silicon Pyranometer does not include the entire solar spectrum, it must be used only in the natural daylight conditions for which it was calibrated. It should not be used under vegetation, artificial lights, in a greenhouse, or to measure reflected solar radiation.
