CS320 Digital Thermophile Pyranometer
The Campbell Scientific CS320 digital thermopile pyranometer measures short-wave radiation (sunlight). The thermopile pyranometer’s black surface uniformly absorbs solar radiation across the solar spectrum, outperforming many silicone-cell pyranometers. The dome shape allows for dew and rain runoff.
- Measurement Range: 0 to 2000 W/m2
- Spectral Range: 385 to 2105 nm
- Calibration Uncertainty: ± 2.6%
- Error due to Clouds: ±2 %
NR-LITE2 Net Radiometer
The NR-LITE2 is a net radiometer manufactured by Kipp and Zonen. It measures incoming and outgoing short-wave and long-wave radiation using two black conical absorbers, one facing upward and the other downward. A single output means that separate short-wave and long-wave radiation, and their upward and downward components, cannot be individually obtained.
- Measurement Range: ± 2000 W/m2
- Spectral Range: 0.2 to 100 µm
- Uncertainty: <5%
SN500SS Net Radiometer
The Apogee SN500SS net radiometer measures four-component net radiation. It has two pyranometers to measure upward and downward solar radiation, and two pyrgeometers to detect upward and downward long-wave radiation.
- Spectral Range (upward looking): 385 to 2105 nm
- Spectral Range (downward looking): 295 to 2685 nm
- Uncertainty: Less than 5%
- Spectral Range: 5000 to 30,000 nm
- Uncertainty: 5%
