NR Lite2 Net Radiometer


Product Description


  • Virtually maintenance free
  • Easy to use

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. In contrast to other sensor designs, NR Lite2 requires no fragile plastic domes. This results in a virtually maintenance free design. The vertical stick prevents birds from affecting the output signal.

The NR Lite2 is easy to use. It is based on a thermopile sensor. The voltage is proportional to the net radiation. It can be directly connected to voltmeter or data logger with an mV input. It has the same high quality yellow cable fitted as our other instruments.
