Apogee's new cost-effective thermopile pyranometers features a blackbody thermopile detector that provides a much broader and more uniform spectral response for better performance in all atmospheric conditions compared to silicon cell pyranometers.
It compares favorably to other thermopile pyranometers at a fraction of the cost. Applications include shortwave radiation measurement in agricultural, ecological, and hydrological weather networks, measurement of global solar radiation, and optimizing photovoltaic systems.
The model SP-510 is a traditional upward looking model, while the SP-610 is downward looking to measure reflected shortwave radiation from terrestrial surfaces.
ISO 9060:2018: Class C (previously known as second class)
Spectral Range: Upward-looking: 385 to 2105 nm Downward-looking: 295 to 2685 nm
