概览
CNR1净辐射表由Kipp & Zonen生产，适用于那些需要研究级性能的应用中。CNR1用于监测能量平衡，测量4个辐射分量：入射短波辐射、入射长波辐射及地表反射短波辐射和地表长波辐射。在结构上，CNR1含有一对朝上的短波辐射表和长波辐射表，以及镜像对称的一对朝下的短波辐射表和长波辐射。短波表和长波表分别测量短波辐射和远红外辐射。CNR1还含有一个铂电阻，用于测量辐射表内部温度；还有一个加热器用于防止凝结。当订购CNR1时，标准的线缆长度为82英尺。如果需要订购定制长度线缆的CNR1，请选择CNR1-L。

CNR1的到货线缆长度为82英尺。该净辐射表适用于要求研究级性能的应用中。CNR1用于监测能量平衡，测量4个辐射分量：入射短波辐射、入射长波辐射及地表反射短波辐射和地表长波辐射。
在结构上，CNR1含有一对朝上的短波辐射表和长波辐射表，以及镜像对称的一对朝下的短波辐射表和长波辐射。短波表和长波表分别测量短波辐射和远红外辐射。4个探头单独校准，具有各自的灵敏度系数。
CNR1还含有一个铂电阻，用于测量辐射表内部温度；还有一个加热器用于防止凝结。
CNR1占用数据采集器上的6对差分通道，或4个单端加上2对差分通道。具有足够模拟通道的数据采集器包括：CR1000、CR3000和CR5000。

Additional Compatibility Information
Do Not use the UT018 crossarm with the 14364 mounting bracket to fasten the CNR1 to a tower leg. The 14264 mounting bracket should be attached directly to a verticle pole.
Data Logger Considerations
The CNR1 uses six differential or four single-ended and two differential analog channels on the data logger.

As a general guide, go at least 1.5 m above the tallest plant (tree) in an ecosystem.

CNR1 is a four-output net radiometer. It gives values for incoming short-wave, incoming long-wave, outgoing short-wave, and outgoing long-wave radiation. It also calculates the net radiation and albedo.
-
If the BR (Bowen Ratio) system is being run on 21X or CR23X dataloggers, a CNR1 net radiometer cannot be used with the system because those data loggers do not have enough input channels. For this reason, Campbell Scientific recommends running a CNR1 out of a separate data logger.
