A nephelometer [1] or aerosol photometer [2] is an instrument for measuring the concentration of suspended particulates in a liquid or gas colloid. A nephelometer measures suspended particulates by employing a light beam (source beam) and a light detector set to one side (often 90°) of the source beam.
The aethalometer has been developed into rack-mounted instruments for use in stationary air quality monitoring installations; transportable instruments which are often used at off-grid locations, operating from batteries or photovoltaic panels in order to make measurements at remote locations; and hand-held portable versions for measurements of ...
Nephelometry is a technique used in immunology to determine the levels of several blood plasma proteins. For example, the total levels of antibodies isotypes or classes: Immunoglobulin M, Immunoglobulin G, and Immunoglobulin A. [1]
The propensity of particles to scatter a light beam focused on them is now considered a more meaningful measure of turbidity in water. Turbidity measured this way uses an instrument called a nephelometer with the detector set up to the side of the light beam. More light reaches the detector if there are many small particles scattering the ...
Morningstar [7] [8] or Venus Life Finder is a planned uncrewed spacecraft to Venus designed to detect signs of life in the Venusian atmosphere. [5] Slated to be the first private mission to another planet, [9] the spacecraft is being developed by Rocket Lab in collaboration with a team from the Massachusetts Institute of Technology. [10]

McFarland standards. No. 0.5, 1 and 2. In microbiology, McFarland standards are used as a reference to adjust the turbidity of bacterial suspensions so that the number of bacteria will be within a given range to standardize microbial testing.
The Portable People Meter (PPM), also known as the Nielsen Meter, is a system developed by Arbitron (now Nielsen Audio) to measure how many people are exposed to individual radio stations and television stations.
