Instrumentation

• A Turbidity Meter is an analytical instrument used to measure the cloudiness or haziness of a liquid caused by suspended particles. It works on the principle of light scattering—the amount of light deflected by particles in the sample is correlated with turbidity levels, expressed in NTU (Nephelometric Turbidity Units). Widely used in water treatment plants, beverage industries, pharmaceuticals, environmental monitoring, and laboratories, turbidity meters ensure water quality control and regulatory compliance.
