NR01-L 4-Component Net Radiometer
NR01-L 4-Component Net Radiometer

The NR01 consists of a pyranometer and pyrgeometer pair that faces upward and a complementary pair that faces downward. The pyranometers and pyrgeometers measure short-wave and far-infrared radiation, respectively.

The NR01 includes an on-board RTD to measure the radiometer’s internal temperature and a 1-W heater that minimizes the formation of dew and melts frost. To reduce current drain, a relay is typically used to turn on the heater only when the solar radiation is less than 20 W/m2.

Campbell Scientific’s CR6 and CR3000 dataloggers can directly measure this radiometer. A CR1000 can also be used, but a 4WPB100 module is required to measure the internal RTD.

Benefits and Features

  • Internal RTD provides temperature compensation of measurements
  • Research-grade performance
  • Internal 1-W heater reduces the formation of dew and melts frost
  • Separate outputs of short-wave and long-wave infrared radiation for better accuracy and more thorough quality assurance
  • Robust—only requiring limited maintenance

The NR01, manufactured by Hukseflux and cabled for use with Campbell Scientific data loggers, is a research-grade net radiometer that measures the energy balance between incoming short-wave and long-wave infrared radiation versus surface-reflected short-wave and outgoing long-wave infrared radiation. Our data loggers measure the NR01's output and control its internal heater. This net radiometer offers a professional solution for scientific-grade energy balance studies.
