Davis 24-Hour Fan-Aspirated Radiation Shield

Product Overview

The Davis 24-Hour Fan-Aspirated Radiation Shield (#7755) is a premium solution designed to maximize the accuracy of temperature and humidity readings for your Vantage Pro2 or Vantage Pro2 Plus (wireless or cabled) weather stations. By drawing a constant airflow through the sensor chamber, it minimizes the impact of solar radiation, ensuring precise data in all conditions. Powered by a solar panel during the day and rechargeable batteries at night, this shield provides continuous operation, making it ideal for professional, agricultural, and research applications where data accuracy is critical.

Key Highlights

• Superior Data Accuracy: A motor-driven fan maintains constant airflow through the sensor chamber at 500 feet per minute (2.5 m/s) during the day, slowing to 280 feet per minute (1.4 m/s) at night, effectively reducing solar radiation effects for precise temperature and humidity readings.

• 24-Hour Operation: Solar-powered during daylight hours with rechargeable batteries for nighttime use, ensuring uninterrupted performance.

• Customizable Sensor Chamber: Features a 2.24” x 3” (56.8 mm x 76.2 mm) sensor chamber to accommodate your existing Vantage Pro2 or Pro2 Plus temperature and humidity sensors.

• Complete Installation Kit: Includes 10 radiation shield plates, rechargeable batteries, mounting hardware, and a 25 ft. (7.6 m) cable for flexible installation.

• Broad Compatibility: Compatible with wireless and cabled Vantage Pro2 (#6152, #6162, #6153, #6163) and Vantage Pro2 Plus (#6162C, #6163C) Integrated Sensor Suites. Not compatible with original Vantage Pro.

• Warranty: Backed by a one-year manufacturer’s warranty for reliable performance.
