The NR01 net radiometer is manufactured by Hukseflux for research-grade energy-balance studies. The radiometer consists of four radiation sensors—two pyranometers measure short-wave radiation and two pyrgeometers measure far-infrared radiation. One upward-facing pyranometer/ pyrgeometer pair measures incoming radiation while a complementary, downward-facing pair measures reflected radiation. The NR01 also includes a resistance temperature device (RTD) to measure the internal temperature and a heater to prevent condensation.
