Overview
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.
Note: NR01 radiometers with a serial number less than 2313 used the pn 21271 fitting. NR01 radiometers with a serial number greater than 2312 do not need the pn 21271 fitting.
Key Advantages
Robust 4-way radiometer that requires little maintenance
Technical Description
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.

Common Accessories
(7)4WPB100
100-Ohm, Four-Wire PRT Bridge Terminal Input Module
Dataloggers other than the CR3000 and CR5000 require the 4WPB100 to measure the NR01's temperature sensor. The 4WPB100 provides completion resistors for measuring 100-ohm Platinum Resistive Thermometers (PRT).

Mounting
To avoid shading or reflections and to promote spatial averaging, the NR01 should be mounted at least 1.5 m above the ground or crop canopy and away from all obstructions or reflective surfaces that might adversely affect the measurement. Campbell Scientific recommends mounting the NR01 to a CM300-series mounting pole at least 25 feet away from other mounting structures. The NR01 is attached to the CM300-series mounting pole via a CM204 or CM206 crossarm.
