COMETEO Professional Multi-Plate Radiation Shield for Weather Sensors

Professional passive solar radiation shield for better protection of meteo sensors and dataloggers and for more accurate measurement, naturally ventilated.

"Not only thermometer screen, but the complete COMETEO system minimizing measurement errors when used with high-quality certified sensors"

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.

Thermometer screen is designed for the installation of sensors with a diameter of 13 to 18 mm.

Also available is the COMETEO F8004 model with four mounting grommets for up to four measuring probes.

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

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

Can be used with most instruments and probes, e.g. Vaisala, Rotronic.
