      The Daytime Fan-Aspirated Shield Kit can be installed on any Vantage Pro2 or PLUS standard ISS model to provide even more accurate temperature and humidly readings.

      The kit contains a solar-powered fan that draws outside air over the temperature and humidity sensors to reduce the effects of daytime radiation on temperature and humidity readings. The solar-powered fan runs during the day. Since there is no backup battery, the fan will cease running when night falls and the effects of the radiation are minimal.

      • The benefits of fan aspiration but half the cost of the Davis 24-hour FARS
      • 75% as effective in reducing the effects of daytime radiation
      • Operating temperature -40° to +150° F (-40° to +65° C)
        Storage Temperature -50° to +158° F (-45° to +70° C)
        Radiation Induced Error +1.0° F (0.5° C) at solar noon (insolation = 1040 W/m2, avg. wind speed ? 2 mph (1 m/s))
        Housing Material UV-resistant plastic
