240-110 NR-Lite2 Net Radiometer

240-110 NR-Lite2 Net Radiometer
The 240-110 NR-Lite2 Net Radiometer is designed for routine measurement of net radiation which is the balance between incoming and outgoing radiation under outdoor conditions.
Product Details

The 240-110 NR-Lite2 Net Radiometer is designed for routine measurement of net radiation which is the balance between incoming and outgoing radiation under outdoor conditions. The detector is based on a Teflon coated, weather resistant black conical absorber. In contrast to other sensor designs, NR-Lite requires no fragile plastic domes. This results in a virtually maintenance free design. The NR-Lite is suitable for:

  • Agricultural Meteorology: Evapotranspiration calculations and crop damage prevention
  • Building physics: Study of thermal stress and heat balance
  • Road Safety: Highway condition monitoring

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 a mV input. The NR-Lite is suitable for conditions outdoor use and fully complies with CE regulations.
