Hukseflux NR01, a 4-component net-radiation sensor
Figure 2 NR01 top view. Standard cable length is 5 m. Cable can be installed / replaced by the user.
Attachement to a 1 inch tube is extremely easy, levelling possibilities are included. Dimensions in mm.
NR01 is a 4-component net-radiation sensor that is used for scientific-grade energy balance studies. The instrument has separate measurements of solar (Short Wave or SW) and Far Infra-Red (Long Wave or LW) radiation. Major improvements relative to comparable instruments include weight (reduced), solar offsets in the LW signal (reduced), ease of leveling (high, because levelling assembly is included).

Introduction
NR01 serves to measure the 4 separate components of the surface radiation balance. Working completely passive, using a thermopile sensors, NR01 generates 4 small output voltage proportional to the incoming and outgoing SW and LW fluxes. The SW solar radiation sensors are also called pyranometers, the LW sensors are also called pyrgeometers. For calculation of sky- and surface temperature, a Pt100 temperature sensor is included in the pyrgeometers.
Figure 1 NR01 4-component net radiation sensor. SW solar radiation sensor or pyranometer (1), LW Far Infra-Red radiation sensor or pyrgeometer (2), radiation shield (3), levelling assembly for x- and y axis (4, 5 and 8).
In order to avoid deposition of dew, the pyrgeometers may be heated. A 2-axis levelling assembly is included.
The NR01 cable can easily be installed or replaced by the user. See also RA01 radiameter on the next page, which is a single side version of NR01. Combined with estimates of SW albedo- and of surface temperature, this instrument can also be used for estimation of net-radiation. For a single pyrgeometer see also IR02.
