Overview

The CNR1 net radiometer by Kipp & Zonen is for applications requiring research-grade performance. The radiometer measures the energy balance between incoming short-wave and long-wave IR radiation versus surface-reflected short-wave and outgoing long-wave IR radiation. The CNR1 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 CNR1 also includes an RTD to measure the radiometer’s internal temperature and a heater that can be used to prevent condensation. The CNR1-L cable length is built to order. For standard lead length of 82 ft, order CNR1.

Technical Description

The CNR1-L has a user-specified cable length. This net radiometer is for applications requiring research-grade performance. It measures the energy balance between incoming short-wave and long-wave infrared radiation versus surface-reflected short-wave and outgoing long-wave infrared radiation.

The CNR1 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. All four sensors are calibrated to an identical sensitivity coefficient.

The CNR1 also includes an RTD to measure the radiometer’s internal temperature, a 4WPB100 module to interface the RTD with the data logger, and a heater that can be used to prevent condensation.

The CNR1 uses six differential or four single-ended and two differential analog channels on the data logger. Data loggers that provide sufficient channels include our CR1000, CR3000, and CR5000.
