CNR2-L

Campbell

The CNR2 features a unique design with separate outputs for short-wave (solar) and long-wave (atmospheric and terrestrial) radiation. The CNR2 fits in the Kipp & Zonen product line between the single output NR-LITE and the four-component CNR1. The glass domes and silicon windows protect the thermopile detectors from environmental factors, minimize the effects of wind and rain on measurements, and are easy to clean.

Features

Kipp & Zonen's CNR2 Net Radiometer measures the energy balance between incoming short-wave and long-wave infrared radiation versus surface-reflected short-wave and outgoing long-wave infrared radiation. It consists of a pyranometer and pyrgeometer pair that face upward and a complementary pair that face downward. The pyranometers and pyrgeometers measure short-wave and far infrared radiation, respectively. Field-of-view is 180 degrees for the upper pyranometer, and 150 degrees for the lower pyranometer. Both upper and lower pyrgeometers provide a 150-degree field-of-view. The CNR2 uses drying cartridges to prevent condensation. Please note that the CNR2 is not compatible with our CR200-series dataloggers.
