Instrument that through optical analysis determines the amount of substances in a liquid, is used in the measurement of particles in suspension in a liquid or dissolved gas, has as its principle of operation the detection of particles with a light beam source and a light detector fixed to 90 degrees from the original beam. It can be a portable or fixed instrument.

The turbidimeter is used to detect turbidity in liquids and aqueous solutions. The precise turbidimeter is used in suspensions. The turbidimeter for water works with the infrared method or the USEPA method. Turbidity is caused by fine substances and not dissolved in a liquid. A cloudy liquid has the property of scattering and reflecting light. The intensity of the reflected light gives information about turbidity.

The turbidimeter displays the value in FTU (Formazine Turbidity Unit). This unit is identical with NTU (Nephelometric Turbidity Unit). The turbidimeter is frequently used in water purification. If we analyze it from a hygienic point of view, the limit values are well below 1 FTU

Operation

From the optical detector, with the light source at 90 degrees, 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 density of particles depends on the properties of the particles such as their shape, color, and reflectivity. The turbidimeter is calibrated with a material commonly known as Arizona street dust. Subsequently, environmental factors (K factors) are used to compensate for light or darker dust. K-factors are determined by the user by activating the turbidimeter near an air sampling pump and comparing the results. Also known as a nehfelometer. The nephelometric turbidity unit (UNT) commonly expressed with the acronym NTU of the English Nephelometric Turbidity Unit, is a unit used to measure the turbidity of a fluid. It corresponds to a concentration of the product used as a pattern called Formacin, which is a solution that can be created using Hydrazine Sulfate and Hexamethylentetraamine in proportions known to form the turbidity pattern of 400 NTU.

Usefulness

The turbidimeter is mainly used in the analysis of air quality to monitor pollution, climate monitoring and visibility. Suspended particles are usually gaseous organic pollutants and dust. Biological contaminants include molds, fungi, bacteria, viruses, animal dander, dust mites, pollens, human skin cells, cockroach parts, and many other things. These are the worst enemies of air quality and are pollutants that cause health problems. The levels of biological contamination depend on the humidity and temperature that allows the survival of the microorganisms. The presence of animals, plants, insects and rodents increases the level of biological contamination. It can be used in the wastewater sector and, in particular, in settling tanks, to measure the amount of suspended solids in water and then establish whether it can be sent to the next level of purification, or if it is pumped directly into the river, sea, or canal.
