Description:
This popular upgrade for the Vantage Pro2 Weather Station upgrades the system's 12-Hour Daytime Fan-Aspirated Radiation shield, or Passive Radiation Shield, to a 24-Hour continuous constant airflow fan. A motor-driven fan draws a constant airflow through the sensor chamber at 500 feet per minute (2,5 m/s). At night, when the effects of radiation are less, this solar-powered model runs on battery power and the airflow slows to 280 feet per minute (1,4 m/s). Install your own sensor in the sensor chamber. Sensor chamber: 2.24” x 3” (56,8 mm x 76,2 mm). Includes 10 plates, rechargeable batteries, mounting hardware, and 25 ft. (7,6 m) cable.

Scientific Sales Input:
One of the best ways to increase the accuracy of your temperature and humidity measurements is to ensure the sensor has a steady flow of air across it. This kit includes upgraded components you'll need to ensure the highest accuracy readings from your Davis weather station, and effectively converts any Vantage Pro2 into a Pro2 Plus. This kit uses the existing Pro2 Weather Station Davis 7346.070 Temperature & Humidity Sensor Board and Davis 7758 Fan Kit, which are also available separately.
