Turbidity refers to the cloudiness or haziness of a liquid caused by suspended particles. It’s crucial to measure because it serves as an indicator of water quality. High turbidity levels can affect aquatic ecosystems, drinking water safety, and the efficiency of treatment processes.

TUR sensors typically utilize optical methods to measure turbidity. They emit light into a liquid sample and measure the amount of light scattered or absorbed by suspended particles. The degree of turbidity is then inferred from the intensity of the scattered or absorbed light.

Turbidity is commonly measured in nephelometric turbidity units (NTU) or Formazin Nephelometric Units (FNU). These units quantify the amount of light scattered by suspended particles in the liquid sample.

TUR sensors are used in various industries and applications, including environmental monitoring, water treatment plants, beverage production, aquaculture, and research laboratories. They help ensure water quality, monitor treatment processes, and assess the clarity of liquids.

Unlike sensors that measure specific chemical parameters like pH or dissolved oxygen, TUR sensors focus on the physical property of turbidity. They provide insights into the presence and concentration of suspended particles in the liquid, which can affect its clarity and quality.

TUR sensors should be calibrated regularly using standardized calibration solutions or reference materials with known turbidity levels. Additionally, periodic verification against certified reference materials or secondary standards helps ensure the accuracy and reliability of measurements over time.
