Model 240 Licor Silicon Pyranometer Sensor

The Licor Silicon Pyranometer is designed for field measurement of global solar radiation in agricultural, meteorological, and solar energy studies. In clear unobstructed daylight conditions, the Licor Pyranometer compares favourably 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. Under most conditions of natural daylight, the error is less than 5%. The current output can be recorded by a data logger such as the Neon or Starlog Data Loggers, and is directly proportional to solar radiation, calibrated under natural daylight conditions in units of watts per square meter (Wm²).

Because the spectral response of the Licor 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.
