The 280-SP Series Silicon Cell Pyranometers are excellent for applications that do not require the higher accuracy and cost of a thermopile pyranometer. They are less expensive and have faster response times, but have higher errors under cloudy conditions.
The 280-SP pyranometers are sensitive in the 360-1120 nm shortwave radiation range and are calibrated to estimate total shortwave radiation across the entire solar spectrum.
The solar radiation sensors consist of a cast acrylic diffuser, photodiode, and signal processing circuitry potted solid in an anodized aluminum housing.
