nephelometric turbidity unit. A unit of measure for turbidity (as measured by a nephelometer). Turbidity is measured by determining the amount of light that is reflected off particles in the water. .
Nephelometric Turbidity Units. The unit used to describe turbidity. Nephelometric refers to the way the instrument, a nephelometer, measures how much light is scattered by suspended particles in the water. The greater the scattering, the higher the turbidity. Therefore, low NTU values indicate high water clarity, while high NTU values indicate low water clarity.
NTU stands for Nephelometric Turbidity Unit which is the unit used to measure turbidity in water. Turbidity refers to the scattering and absorption of light rather than transmission caused by suspended matter such as clay, dissolved organic material and microscopic organisms.
Nephelometric turbidity unit - amount of turbidity (cloudiness) in a water sample.
nephlometric turbidity units.
network terminating unit. In X.25 communications, the point of access to the network.
Network Termination Unit. Equipment to facilitate DSL network access at customer premises. Also called a router.
Nephelometeric Turbidity Units – a measurement obtained by passing a light beam through a low-turbidity water sample with a nephelometer.
Nephelometric turbidity unit. The unit of measure for turbidity.
abbreviation for nephelometric turbidity unit, a unit used in measuring water quality. Turbidity is an optical property: the scattering and absorption of light by solids suspended in water. In other words, water is turbid if you can't see through it. An instrument called a nephelometer (from a Greek word meaning "cloudy") measures turbidity directly by comparing the amount of light transmitted straight through a water sample with the amount scattered at an angle of 90° to one side; the ratio determines the turbidity in NTU's. The instrument is calibrated using samples of a standard solution such as formazin, a synthetic polymer. Drinking water should not have a turbidity above 1 NTU, although values up to 5 NTU are usually considered safe. Outside the U.S., this unit is usually called the FNU (formazin nephelometric unit).
Nephelometric Turbidity Unit - a measurement of particles in water
Nephelometric Turbidity Units. Unit of scientific measurement used to represent the level of suspended material in solution.
nephelometric turbidity unit. unit of measure for the turbidity of water. Essentially, a measure of the cloudiness of water as measured by a nephelometer. Turbidity is based on the amount of light that is reflected off particles in the water.
Nephelometric turbidity unit (a unit of measurement for turbidity).
Nephelometric Turbidity Unit (water chemistry)
Nephelometric Turbidity Units. Unit of turbidity measurement. A device measures the transmission or reflection of light by the particles causing turbidity or cloudiness of the liquid.
nephelometric turbidity units. A unit of measure for turbidity values. Turbidity measured in NTU uses nephelometric methods that depend on passing specific light of a specific wavelength through the sample.
A measure of the clarity of water.
Network Terminating Unit. Device serving as interface between customer premise equipment and the carrier facility, regenerating and conditioning digital signals in both directions.
nephelometric turbidity unit. An arbitrary unit of measuring the turbidity in water by the light scattering effect of fine suspended particles in a light beam.
Normal Trading Unit. Standard minimum size of a trading unit for a particular security--more commonly referred to as a "round lot". Stocks typically have a normal trading unit of 100 shares. However, inactive stocks may have normal trading units equal to 10 shares. Any amount of shares less than a round lot is called an "odd lot". See: Inactive Stock/Bond; Odd Lot; Round Lot
