What is a major component of a turbidimeter?

A turbidimeter is an instrument specifically designed to measure the amount of turbidity or cloudiness in water, which is usually caused by suspended particles. The major component that makes this measurement possible is the light source.

In a turbidimeter, the light source emits a beam of light that passes through the water sample. As the light interacts with the particles suspended in the water, it scatters in various directions. The amount and angle of this scattered light are critical for determining the turbidity level. By quantifying how much light is scattered, the turbidimeter can provide an accurate measurement of the concentration of suspended particles in the water.

While water sampling tubes, flow meters, and temperature sensors are important in water quality assessment and monitoring, they do not directly contribute to the measurement of turbidity in the same way that the light source does. This is why the light source is considered the major component of a turbidimeter.
