Description

  • Application circuit uses a photometric front end and a network of 860 nm infrared (IR) emitters and silicon PIN photodiodes to achieve a water turbidity measurement system. Turbidity is an important water quality indicator for the presence of dispersed or suspended solids, which affects potable water and environmental conditions. Turbidity is a qualitative characteristic imparted by how these suspended solids obstruct the transmittance of light. Turbidity is not a direct measure of suspended particles in water but rather a measure of the scattering effect that such particles have on light
