Young - Model 43502 -Aspirated Radiation Shield

The Aspirated Radiation Shield provides maximum sensor protection from incoming short wave and outgoing long wave radiation.  The shield employs a triple walled intake tube and multiple canopy shades to effectively isolate the sensor from precipitation and solar radiation. A continuous duty DC blower provides constant flow of ambient air over the sensor. A tachometer output may be used to monitor blower operation.  A variety of temperature and relative humidity probes are available.
