NR Lite2 is designed for routine measurement of net radiation which is the balance between incoming and outgoing radiation under outdoor conditions. The design of the NR Lite2 is unique. The double-sided detector has black conical absorbers with an anti-stick weather resistant protective coating. The NR Lite2 has a virtually maintenance free design. The output voltage is proportional to the net radiation. It can be directly connected to voltmeter or data logger with an mV input.
