Atmospheric visibility is defined as the maximum ground level distance at which a person with normal vision can see the target clearly under the prevailing weather conditions. The atmospheric visibility measuring instrument 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.

The atmospheric visibility measuring instrument can adapt to various severe weather conditions, and the integrated design makes the layout of the internal cables more reasonable. The lens of the optical component is facing down and has a protective cover, which can effectively prevent precipitation, droplets or dust from entering the lens, and reduce the pollution of the probe surface. This design provides accurate measurements and reduces maintenance requirements. The overvoltage and electromagnetic protection devices of the sensor will ensure the long-term safe operation of the sensor.

It is widely used in road weather information system, fog detection network, airport weather system, cooling tower smoke detection, weather monitoring, port security.
