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.
