Turbidity Meter

A turbidimeter is a device that evaluates how cloudy a liquid is—that is, it determines turbidity. This is done through an optical analysis that allows you to measure the suspended particles in a dissolved gas or in a liquid. It uses a light source and a light detector (a photocell) fixed at a right angle to the original beam.

Turbidity is a measure of the opacity or nebulosity of a fluid. It is considered an essential analysis to determine the water quality, because it is caused by particles of different sizes and that generate an opaque appearance in the sample, and will be higher because there is a greater proportion of undissolved solids in the liquid. Although it is important to note that turbidity is a measure of the opacity of a liquid, it is not a measure of real particles.

Our Best Selling Turbidity Meter

The turbidimeter shows the rate or ratio of luminous intensities, it measures both the transmission of light intensity and its dispersion. This is of vital importance for liquids that are brightly colored and for samples of high turbidity.

Turbidity Meter Operating

A turbidimeter measures suspended particles with a beam (beam source) and a light detector fixed at 90° from the original beam. The density of the particles is a function of the light reflected by the particles suspended in the detector. The amount of light reflected for a given particle density depends on the properties of the particles such as their shape, color, and reflectivity.

Turbidity can be estimated with equipment such as the spectrophotometer and the colorimeter, which can measure the decrease in transmitted light due to the blockage generated by particles. However, these measurements are not considered valid by the international regulatory bodies because they do not comply with the accepted definition of turbidity, they propose at all times the use of the turbidimeter.
