Radiation Shield for Weather Sensors, actively ventilated with built-in fan

Professional actively ventilated solar radiation shield for better protection of thermometers hygrometers barometers CO2 meters and dataloggers for more accurate measurement.

Multiplate radiation shield is used to protect measuring devices and provides more accurate measurement results. The shield minimizes radiation reaching the sensor, minimizes radiation absorbed by the shield and maximizes ambient air flow around the tube with sensor. The enlarged 200mm diameter of 13 plates is designed to provide full protection of measuring device.

Optimized design combines all excelent features of multi-plate shield with effective active ventilation by means of a high performance fan powered from external 12Vdc voltage. The unique design allows the use of a low energy fan that minimizes potential sensor's parasitic heating from the fan motor.

The most important advantage of artificial ventilation of the shield is the reduction of the daytime radiation error especially in calm days with low winds.
