Meaning and Definition
A scientific instrument that measures the extinction coefficient or transmittance of the atmosphere, typically for assessing visibility or the clarity of air or water.
A device used in meteorology, oceanography, and environmental science to quantify how much light or electromagnetic radiation passes through a medium (e.g., air, water). The measurement is crucial for determining visual range, water clarity, or atmospheric particulate concentration.

FAQ
Frequently Asked Questions
They are related but not identical. A transmissometer measures the beam attenuation or transmission of light. A turbidity meter typically measures the scattering of light, which correlates with but is not the same as transmission. In practice, the terms are sometimes used interchangeably in water quality contexts.
They are commonly found at major airports (to measure runway visual range), on oceanographic research vessels (to measure water clarity), and at environmental monitoring stations.
Yes, but the design and calibration differ significantly due to the different optical properties of the two mediums. An atmospheric transmissometer has a longer path length, while an underwater one is designed for high pressure and potential biofouling.
It refers to a very specific piece of professional equipment. Outside of meteorology, oceanography, and related engineering fields, there is no need for the general public to use or encounter this term.
