Digital turbidity meter is a tool used to gauge the turbidity of a water sample. The number of suspended particles in water is measured by turbidity, which is frequently used as a proxy for water quality. Compared to older, analogue turbidity metres, our device is typically more accurate since they employ light scattering to measure turbidity. It is a technique for figuring out how many particles are suspended in a media as precipitates or aggregates. Digital turbidity meter tests the presence of lead, calcium, etc. using a qualitative limit.
