COMETEO Professional Thermometer Screen for Weather Station Sensor

Professional radiation shield for protection of temperature sensors or combined temperature/humidity sensors, weather monitor and datalogger.
Passive, naturally ventilated.

WINNER of the Intercomparison of Thermometer Screens in the Arctic under the auspices of the World Meteorological Organization – WMO

Multi-plate radiation shield is used to protect weather monitor systems and provides the most accurate climate measurement results. The uniquely designed screen minimizes solar radiation reaching the sensor, minimizes radiation absorbed by the screen and maximizes ambient air flow around the weather station sensor. The surface exposed to sunlight is made of highly reflective UV and long-term stable ASA plastic. The inner surfaces of the screen are made of matt black plastic to minimize internal reflections. Large 210mm diameter of 14 plates is designed to provide full protection of weather sensor.

Each of the fourteen black louvres is equipped with a circular slot allowing air to flow vertically through the entire radiation shield. The slot also separates the sunlit part of the louvre from the inner part and thus prevents heat transfer to the sensors.

Cylindrical space with 110mm diameter and 210mm height is available inside of the plates for installation of entire climate measuring device with minimized solar radiation.

Excellent wasp and bug deterrence. Sophisticated design prevents insects from building nests inside and thus degrading measurement.

Low cost stable replacement for Stevenson screen, taking advantage of reduced maintenance and better performance due to the low time constant compared to the traditional Stevenson screen.

Works with COMET instruments and most professional weather equipment.
