Turbidimeters are measuring devices, they determine the amount of particulate solids in a liquid. This measurement is, for example, part of the examination within the framework of the Drinking Water Ordinance, or also in beer production for measuring the amount of yeast or in milk in dairies. These devices are available either as inline devices for installation in piping systems or as stand-alone devices. Usually, these instruments are equipped with a powerful optical light source that uses, for example, the infrared light of a tungsten filament or laser light to shine through the liquid under examination. Due to this structure, the limits of applicability are also given. Modern measuring systems work more and more with LEDs as light sources. The instruments do not measure the absorption of radiation across the spectrum of different wavelengths, as spectrometers do, but rather the attenuation of light intensity overall due to scattered light formation and absorption. Turbidimeters are the subject of photometry. The accuracy of the instruments can be further increased when using a dual-beam measurement method, i.e. a method in which two detectors and a semi-transparent mirror are used, compared to the more cost-effective single-beam method.
What are turbidity meters and what are they used for?
Turbidity meters are instruments that are used to measure the turbidity of a liquid or gas. Turbidity refers to the amount of suspended particles or light scattering in a liquid or gas. The more particles or scattering are present, the cloudier the substance becomes.
Turbidity meters use different methods to measure turbidity. A frequently used method is light scattering. The device sends a beam of light through the liquid or gas and measures the scattering angle or the intensity of the reflected light. The higher the scattering or intensity of the reflected light, the cloudier the substance.
Turbidity meters are used in various applications. In environmental monitoring, they are used to measure the turbidity of river and sea water, which can indicate pollution by sediments or other particles. They are used in the food industry to check the quality of drinks, dairy products and other liquids. They are used in the pharmaceutical industry to monitor the purity of medicines. Turbidity meters are also used in water treatment, the chemical industry and other areas where turbidity is an important parameter.

How do turbidity meters work and how is turbidity measured?
Turbidity meters are used to measure the degree of turbidity or cloudiness in a liquid. Turbidity is a measure of the scattering of light in the liquid caused by the presence of suspended particles such as solids, suspended matter or droplets.
There are different types of turbidity meters, but generally they use a beam of light sent through the liquid to measure turbidity. The light beam is scattered by the particles in the liquid and this scattering is recorded by a detector in the measuring device.
There are various methods for measuring turbidity. A frequently used method is nephelometry. The light beam is sent to the liquid at a certain angle and the detector measures the intensity of the scattered light. The higher the turbidity of the liquid, the more light is scattered and the higher the measured intensity.
Another method is the so-called transmission method. Here, the light beam is sent directly through the liquid and the detector measures the intensity of the transmitted light. The higher the turbidity of the liquid, the less light is transmitted and the lower the measured intensity.
Turbidity meters can be used in various applications, such as in water and wastewater treatment, in the food industry, in the pharmaceutical industry and in environmental monitoring. They enable the turbidity to be measured quickly and accurately in order to monitor the quality and purity of liquids and make adjustments if necessary.

What types of turbidity meters are there and what are the differences between them?
There are different types of turbidity meters that use different measuring principles depending on the area of application. Here are some examples:
1. Nephelometer: A nephelometer measures turbidity by measuring the amount of scattered light from a laser beam or light source that is reflected by the particles suspended in the liquid or air. The higher the turbidity, the more light is scattered.
2. Turbidimeter: A turbidimeter uses a light source and a detector to measure the absorption and scattering of light by the suspended particles in a liquid. It measures the turbidity based on the change in light passing through the sample.
3. Turbidity sensor: A turbidity sensor consists of a light source and a photodetector that face each other. It measures the turbidity by determining the difference between the incident light intensity and the detected light intensity. The higher the turbidity, the greater the difference.
The differences between the various turbidity meters can lie in the accuracy, sensitivity, measuring range, measuring method and application. For example, some devices are better suited to measuring turbidity in liquids, while others are suitable for measuring turbidity in the air. Some devices can also measure other parameters such as particle size distribution or particle concentration. The choice of the right device depends on the specific application and requirements.
