The purpose of a meteorological screen is to shield instruments against precipitation and direct heat radiation from outside sources, while still allowing air to circulate freely around them.
The screen creates, as near possible, a uniform environment in relation to the air outside. The Stevenson screen is designed to hold Maximum and Minimum thermometers of the mahogany-frame pattern as well as a Kew Pattern Hygrometer, but can readily be adapted to accept equivalent thermometers of other patterns. The screen is available in finished form, ready for use and is manufactured from high quality, seasoned wood. The front panel hinges at the bottom to form a door, and is retained in the horizontal position by two safety chains. The door can be padlocked shut. The whole screen is painted with several coats of white paint to reflect radiation.
