The Wind Speed and Outdoor Temperature outputs are fed into the microprocessor and the calculated resultant wind chill is displayed. The calculations are based upon the equation developed by Dr. Paul Siple from tests made at Antarctica. Supplied with 40 feet of connecting cable. The sensor is temperature compensated by the microprocessor. Switch provided to change from inches to millimeters.
System records accumulation for any period plus current rainfall.
The gauge meets the NWS specifications for collector size. It is unharmed by freezing, however count accuracy during such periods is suspect. The amount displayed times ten is the number of Heating Degree Days for the time period involved. The amount displayed is the number of Cooling Degree Days for the time period involved. The masthead sensor unit includes the instruments for wind speed, wind direction, and rainfall.
