Turbidity

Turbidity meters are instruments used to measure how clear or cloudy a liquid is. That cloudiness, called turbidity, is caused by tiny particles floating in the water that you sometimes can’t see with the naked eye. These meters are used in a wide range of applications, from testing drinking water and monitoring rivers and lakes to managing industrial and wastewater systems.

They work by shining light through the water and measuring how much of it gets scattered by the particles. The more scattering, the cloudier the water. The results are usually given in NTU (Nephelometric Turbidity Units). This is a standard unit for measuring turbidity.

Turbidity meters come in different types depending on your needs. Portable handheld devices for fieldwork. Benchtop models for labs, and even systems designed for continuous monitoring in real-time.

When choosing a turbidity meter, think about what you’ll use it for. How precise it needs to be, how easy it is to calibrate, whether it stores data, and if it meets industry standards like EPA or ISO.
A good turbidity meter is a must-have for getting clear, accurate results.
