The T351 range of compact, lightweight, low-maintainance, naturally ventilated solar radiation screens is suitable for use with a wide range of air temperature and air humidity probes which are on the market. It is an ideal add-on to reduce errors due to the sun heating unprotected probes, a number of variants being available to suit different probe dimensions.
The T351 Miniature Screen forms the housing for a range of air temperature sensing elements (or humidity and combined temperature/humidity sensing elements), providing weather protection while allowing the free passage of air.
The circular design with white polished surfaces reduces sensing element measuring error due to temperature rise caused by solar radiation during the day, and errors due to outward radiation to clear skies at night.
Apart from the more rapid thermal response, the performance is comparable to that of the traditional Stevenson Screen.
