In the vast mist, when the naked eye finds it difficult to distinguish distant scenes, the forward scattering instrument is "seeing clearly" the world in its unique way. This instrument based on the principle of forward scattering accurately calculates the current visibility value for us by measuring the total extinction coefficient of the air, and has become an indispensable "sharp eye" in the fields of meteorological monitoring and traffic safety.
The working principle of the WX-N5 forward scattering instrument is quite poetic. Unlike traditional transmissibility visibility meters that require long-distance optical path layout, it ingeniously utilizes the scattering characteristics of light in the air. When a light beam passes through the air, it interacts with the particulate matter in the air, generating scattered light at a specific Angle. The forward scattering meter precisely captures these scattered light signals in specific directions, inversely deduces the total extinction coefficient of the air, and then calculates the accurate visibility value. This "point-to-surface" measurement method not only saves space but also ensures accuracy.
In practical applications, the forward scattering meter has demonstrated unique advantages. Its measurement is not affected by day or night. Whether it is a sunny noon or a pitch-dark late night, it can work stably. Meanwhile, it has relatively loose requirements for the installation environment and does not need to maintain a long-distance straight optical path like traditional equipment. This makes it particularly suitable for use in places with limited space, such as airport runways, highways, port terminals and other critical locations.
What is even more commendable is that the measurement results of the forward scattering instrument have excellent real-time performance and continuity. It can continuously monitor changes in visibility and promptly detect the formation and development trends of weather phenomena such as fog, haze and sandstorms. This capability is particularly important for fields such as air traffic control, highway early warning, and maritime safety, where real-time visibility conditions need to be grasped, providing reliable data support for the decision-making of relevant departments.
