NR-LITE2 Net Radiometer
1. Introduction
The NR-LITE2 is a high-output thermopile sensor which measures the
algebraic sum of incoming and outgoing all-wave radiation (both short-wave
and long-wave components). Incoming radiation consists of direct (beam) and
diffuse solar radiation plus long-wave irradiance from the sky. Outgoing
radiation consists of reflected solar radiation plus the terrestrial long-wave
component.
The NR-LITE2 is equipped with PTFE-coated (polytetrafluoroethylene) sensor
surfaces. This results in a robust design which provides easy maintenance and
good sensor stability. However, this design is slightly less accurate than the
more traditional radiometers which use plastic domes.
Before using the NR-LITE2, please study:
• Section 2, Cautionary Statements
• Section 3, Initial Inspection
• Section 4, Quick Start
2. Cautionary Statements
• Although the NR-LITE2 is rugged, it is also a highly precise scientific
instrument and should be handled as such.
• Care should be taken when opening the shipping package to not damage or
cut the cable jacket. If damage to the cable is suspected, consult with a
Campbell Scientific applications engineer.
• When installing the NR-LITE2, use only the support arm to rotate the NR-
LITE2. Using the sensor head to rotate the instrument may damage it.
3. Initial Inspection
• Upon receipt of the NR-LITE2, inspect the packaging and contents for
damage. File damage claims with the shipping company.
• The model number and cable length are printed on a label at the
connection end of the cable. Check this information against the shipping
documents to ensure the correct product and cable length are received.
• Refer to Section 3.1, Ships With, to ensure that parts are included.
