NR-LITE2 是一款坚实耐用的净辐射表,测量入射短波辐射和长波红外辐射,相对于地表反射的短波辐射和向上长波红外辐射的能量平衡。它可以直接连接到坎贝尔的数据采集器,广泛用于农业和水文应用中。
NR-LITE2 包括两个黑色的圆锥形吸收体,一个朝上,另一个朝下。它们涂有PTFE涂层,这使得它们具有耐候特性,因而不需要脆弱的塑料罩。两个吸收体都被校准到相同的灵敏度系数。
NR-LITE2 的水平泡可帮助确保合适的安装;所配备的小棒防止鸟儿栖息在传感器。传感器产生微伏信号,由坎贝尔数据采集器直接测量。

To avoid shading/reflections and to promote spatial averaging, the NR-LITE2 should be mounted at least 1.5 m above the ground or crop canopy and away from all obstructions or reflective surfaces that might adversely affect the measurement. Campbell Scientific recommends mounting the NR-LITE2 to a separate vertical pipe at least 25 ft away from other mounting structures. The 26120 Net Radiation Sensor Mounting Kit is used to mount the NR-LITE2 to a vertical pole or a horizontal crossarm, such as the CM202, CM203, CM204, or CM206.
