AT/RH Radiation Shield

AT/RH Radiation Shield



Multi-Plate, Free-Flowing Radiation Shield


  • Protects temperature and relative humidity sensors from error producing solar radiation and precipitation.
  • Compact size and light weight make this shield useful for many applications.
  • Naturally ventilated, requires no power
  • Used with ambient temperature sensors
  • Useful for a wide range of applications
  • Well suited for field studies where power for aspiration is not available
  • Easy air passage through shield
  • Unique shape of disc provides positive blockage of direct solar radiation, as well as reflected radiation from the temperature sensing element.
  • Specially formulated thermoplastic disc material for maximum weatherability, high reflectivity, low thermal conductivity, and low heat retention.
  • Accommodates variety of sensors through threaded plastic hex plug (sensors up to 1 in. (26mm) dia.).
