Turbidity meter
A turbidity meter is a device that allows to evaluate how turbid a liquid is, i.e. it determines the turbidity. It does this through an optical analysis that allows it to measure the particles in suspension in a dissolved gas or liquid. It uses a light source and a light detector (a photocell) fixed at right angles to the original beam.
Turbidity is the measure of the opacity or haziness of a fluid. It is considered an essential analysis to determine the quality of water, because it is caused by particles of different sizes that generate an opaque appearance in the sample, and it will be higher when there is a higher proportion of undissolved solids in the liquid. Although it is important to keep in mind that turbidity is a measure of the opacity of a liquid, it is not a measure of actual particles.

Laboratory Turbidimeter: What are the different types that exist?
These devices allow us to measure the turbidity of water, being turbidity an indicator of water quality
Kalstein Turbidimeters
Turbidimeters are equipment that through optical analysis measure the turbidity of a liquid. That is, they are devices capable of measuring the size and concentration of particles in a suspension by diffusing light at 90 ° in a tube. It can be portable or fixed.

Turbidity Meter in Operation
Turbidity can be estimated with equipment such as the spectrophotometer and colorimeter, which can measure the decrease in transmitted light due to blockage generated by particles. However, these measurements are not considered valid by international regulatory bodies because they do not meet the accepted definition of turbidity, and they always propose the use of the turbidity meter.
A turbidity meter is designed for field or laboratory measurements, as well as for uninterrupted monitoring through the setting of an alarm that is activated when unsafe turbidity levels are reached. Turbidimeter setup is an essential element for good turbidity measurement performance. The turbidity unit used by turbidity meters is the NTU (nephelometric turbidity unit), and they usually have a measurement range from 0 to 2000 NTU in the most sophisticated instruments. The latest technology for turbidity measurement uses a laser to measure light scattering at 90° and 360° around the sample, offering high optical accuracy, fast results and increased equipment reliability.
