The NR01 net radiometer is manufactured by Hukseflux for applications requiring research-grade performance. The radiometer measures the energy balance between incoming short-wave and long-wave infrared radiation versus surface-reflected short-wave and outgoing long-wave infrared radiation. It 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 RTD to measure the radiometer’s internal temperature and a heater that can be used to prevent condensation. Most of our dataloggers require a 4WPB100 module to interface the RTD with the datalogger.
