Stevenson Screen Model 306

Quick Overview

The lightweight Radiation Shield model 306 is a small Stevenson screen designed to protect temperature and relative humidity sensors against error-producing solar radiation and precipitation. The shape of the shield allows optimum wind flow between the discs, whilst prevent rain and the heat from the Sun affecting the sensors readings. The white UV stabilized thermoplastic discs offer a high reflectivity, low thermal conductivity and rugged weather resistance. The screen can be mounted directly to a wall, or to a mounting pole with diameters up to 27mm. Sensors are secured by the M26 compression gland fitted to the bottom of the bracket and is the ideal size for securing a standard HygroClip 2 temperature and humidity probe.
