Nephelometers are devices used to measure the concentration of suspended particles in a liquid or gas by analyzing light scattering, providing accurate and reliable turbidity measurements. They are used in applications such as water quality monitoring, environmental studies, and industrial processes, ensuring precise determination of particle concentration. Nephelometers offer features such as high precision, digital displays, and calibration capabilities, making them essential for maintaining the quality and clarity of liquids and gases. Their ability to provide reliable turbidity measurements makes them valuable for ensuring environmental safety and process efficiency.
