Turbidity is the phenomenon of light scattering caused by impurity particles or other components in a body of water, and a turbidity sensor is a device used to measure the concentration of particulate matter in a body of water. Turbidity measurement technology has been widely used, such as water treatment, food production, pharmaceutical industry, environmental monitoring and other fields.
1. Principle of Turbidity Sensor
Turbidity sensor is based on the principle of light scattering, that is, by detecting the light scattered in the water body to measure the concentration of particles in it. Its key instrument components are laser or white light source and photodiode (or photodiode array), such a combination can be realized in a single point or multi-point measurement.
In addition to relying on raw data, the turbidity sensor can be used to obtain the extent of particle distribution and particle morphology, and can observe the location and number of particles or combustion debris. Accordingly, we can utilize this instrument for high-precision measurements of particle concentrations in various water bodies.


2. Application of Turbidity Sensor
The measurement of turbidity is not only related to the color of a body of water. It is also an important means of detecting the presence of untreated pollutants in a body of water that exceed environmental standards.
(1)Water Treatment
Water is a necessary resource in our life, but in recent years, with the growth of population and the acceleration of industrialization, water resources are becoming more and more polluted. The turbidimeter is a very important means of water quality testing. The use of turbidity testing technology, you can quickly, accurately and intuitively analyze the concentration of particulate matter in the water body, thus avoiding the inability to timely detection of pollutants in the water.
(2)Pharmaceutical Industry
In the pharmaceutical industry, turbidimeter is widely used to analyze the purity and turbidity of drugs. This technology is very important for pharmaceutical factories, because good quality is a process of creating credibility, and the quality of drugs is directly related to the safety of people's lives. Therefore, pharmaceutical production and sales need to use turbidity sensors to ensure the stability of their product quality.
(3) Chemical Industry
Turbidity measurement technology in the chemical industry is also very important. For example, this technology can detect the concentration of particles in liquids during the production process, as well as the concentration of particles related to droplet dynamics. Utilizing this technology, we can better understand process performance and data distribution, thus improving production efficiency.
(4)Environmental Monitoring
Turbidity sensors can be used for monitoring of various environments. Measuring the turbidity of a body of water can provide early screening for contaminants, thus helping to protect the environment and protect public health. The use of turbidity sensors in process control and quality control ensures the generation of clean and safe drinking water and the control of chemical industry waste and industrial wastewater discharges.
Turbidity sensors are an accurate and widely used analytical technique that has been applied in a wide range of industries such as water treatment, food production, pharmaceuticals, and environmental monitoring. By measuring the scattered light from particles or other components of water, this technique can provide valuable information on environmental pollution, pharmaceutical product quality, and more. Therefore, turbidity sensors will continue to be an important tool for high-precision measurement and quality control.
