The NR-LITE2 includes two black conical absorbers—one facing upward and the other facing downward. The absorbers are coated in PTFE, making them resistant to weather without using a fragile plastic dome. Both absorbers are calibrated to an identical sensitivity coefficient.
The NR-LITE2 has a bubble level to ensure proper installation and a rod that deters birds from roosting on the sensor. It produces a millivolt signal that is measured directly by a Campbell Scientific data logger.
Benefits and Features
- Compatible with most Campbell Scientific data loggers
- Integrated bubble level ensures proper installation
- Includes rod that deters birds from roosting on the radiometer
- PTFE-coated absorbers are weather-resistant without using a fragile plastic dome
The NR-LITE2, manufactured by Kipp & Zonen and cabled for use with Campbell Scientific data loggers, is a rugged net radiometer that measures the energy balance between incoming short-wave and long-wave infrared radiation relative to surface-reflected short-wave and outgoing long-wave infrared radiation. It is directly connected to a Campbell Scientific data logger and is widely used in agriculture and hydrology applications.
- NR-LITE2-L Net Radiometer measures the energy balance between incoming short-wave and long-wave infrared radiation relative to surface reflected short-wave and outgoing long-wave infrared radiation.
- Includes two black conical absorbers—one facing upward and the other facing downward.
- The absorbers are coated in PTFE, making them resistant to weather without using a fragile plastic dome.
- Calibrated to an identical sensitivity coefficient.
- Includes a bubble level to ensure proper installation and a rod that deters birds from roosting on the sensor.
- Produces a millivolt signal that is measured directly by a Campbell Scientific data logger.
- The only difference between the NR-Lite and the NR-Lite2 is the color of the wires.
