Atmospheric visibility is defined as the maximum horizontal distance on the ground at which a person with normal vision can still see the outline of the target clearly under the prevailing weather conditions. The atmospheric visibility meter determines the visibility distance by measuring the intensity of scattered light caused by gas molecules, aerosol particles, fog droplets, etc. in a certain volume of air.
ES-AVS-309 atmospheric visibility sensor independently developed by our company can adapt to various severe weather conditions, and the integrated design makes the layout of the internal cables more reasonable. The optical component lens is facing downward with a protective cover to effectively prevent precipitation, droplets or dust from entering the lens and reduce the contamination of the probe surface. This design provides accurate measurement results and reduces the need for maintenance. The overvoltage and electromagnetic protection devices of the visibility meter can ensure the long-term safe operation of the sensor. It is widely used in road meteorological information systems, fog detection networks, airport meteorological systems, cooling tower smoke detection, meteorological monitoring, and port safety.
