Portable Visibility Meter

SISCO-TH-BN10

The portable visibility meter uses the forward scattering method to measure the total extinction coefficient of the air and calculate the current visibility. The measuring range is 10km/20km, the digital interface uses RS232, active uploading, and 24V power supply. The visibility meter is equipped with a high-definition touch screen that displays data curves in real time. Visibility detector with wireless transmission, built-in rechargeable lithium battery with a capacity of 6.6AH, and an operating temperature of -20°C~60°C. Digital visibility meters can be used in traffic, outdoor activities, weather pollution, etc. that require dynamic understanding of environmental visibility.

A visibility meter, also known as a meteorological visibility measuring instrument, is a scientific device specifically designed to measure the transmission of visible light through the atmosphere. The primary function of this device is to measure and display the maximum distance at which people can see and identify objects under specific conditions.

The working principle of a visibility meter instrument is primarily based on the theory of light propagation and scattering. When light passes through the atmosphere, it is scattered and absorbed by air molecules, aerosol particles, water droplets, and other substances, thereby affecting its propagation distance and intensity. By measuring these changes, the portable visibility meter can calculate the visibility in the atmosphere.

Visibility sensors have a wide range of applications, primarily in meteorological observation, aviation, navigation, road transportation, and environmental monitoring. For example, in aviation, visibility meters help pilots assess flight conditions to ensure flight safety; in road transportation, they assist drivers in evaluating road conditions to prevent traffic accidents.
