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.

Detailed 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.

Frequently Asked Questions
Number of FAQs related to CNR1-L: 1
-
The CR1000 requires a 4WPB100 to measure the internal PRT. (Data loggers such as the CR3000 and CR5000 have the necessary PRT bridge module built in to measure the PRT.) Note that the CNR4-L also includes an internal thermistor, which can be directly measured by the CR1000. Because of this, when using a CR1000, Campbell Scientific typically recommends monitoring the internal temperature of the CNR4-L using its internal thermistor instead of the PRT.
