Scattering Method Online Turbidity Sensor Anti Interference

KTU310 Online Turbidity Sensor 90 ° Angle Scattering Principle Fiber Structure, Strong Anti-Interference Ability

1.Principle

The KTU310 integrated online turbidimeter is designed and made by the principle of scattering light turbidimeter. When a beam of light enters a water sample, the light is scattered by the turbidity material in the water sample. The turbidity in the water sample can be calculated by measuring the intensity of the scattered light in the vertical direction of the incident light and comparing it with the internal calibration value, the final value is output after linearization.

Tips: Measuring Turbidity through Water Clarity Methods

While most secchi discs alternate black and white quadrants, oceanographic discs tend to be all white.

Water clarity and turbidity are directly related. In any body of water, the higher the turbidity, the lower the water clarity will be. However, while one is often an indicator of another, measurements between the two parameters are not interchangeable.

Water clarity is measured by a Secchi disk. Named after Angelo Secchi, these discs are usually quartered in black and white, though solid white and solid black discs are used in certain environments.

Secchi disks are used in lakes, oceans, and deep rivers, where they are lowered into the body of water until they are no longer visible. Then they are slowly raised back to the last point of visibility, and that depth is recorded. The depth at which visibility is lost is known as the Secchi depth (7). High Secchi depths are associated with high water clarity and low turbidity, while low Secchi depths indicate high turbidity.

Secchi disk readings rely on light attenuation in water. In other words, they measure the depth of visibility based on light penetration ⁹. When the disk is underwater, light reflects off it, making the disk visible to the human eye. When the disc is obscured by suspended sediment, algae or dissolved colored material, the light is no longer directly reflected to the viewer ⁹. Instead, it is scattered and diffused. The more scattered the light becomes, the less visible the disc will be until it disappears completely.
