The NR01 is a four-component net radiometer. This product is applicable for scientific-grade energy balance studies. It can operate with a separate measurements of solar and Far Infra-red radiation. It has major developments relative to comparable instruments including weight, solar offsets in the LW signal, ease of leveling.
This product usually measures four components of the surface radiation balance. It generates four small output voltage equivalent to the incoming and outgoing short wave (SW) and long wave (LW) fluxes using a thermopile sensors. The SW solar radiation sensor are also called pyranometers while the LW sensors are known as pyrgeometers. The pyrgeometers include Pt100 temperature sensor for calculation of sky and surface temperature.
