    Turbidity meter applications

    Tips: What are the types of turbidity meters?

    Turbidity meters, also known as turbidimeters, are instruments used to measure the degree of turbidity or cloudiness in a liquid sample. There are several types of turbidity meters available, each with its own principles of operation and applications. Here are some common types:

    • Nephelometric Turbidity Meter: This type of turbidity meter measures the scattering of light at an angle of 90 degrees to the incident light. It uses a light source and a detector placed at a right angle to each other. The intensity of light scattered by suspended particles in the sample is measured, and the turbidity value is determined based on the amount of scattered light.
    • Absorption Turbidity Meter: These meters measure the reduction in the intensity of light passing through the sample due to the absorption by suspended particles. The decrease in light transmission is directly proportional to the turbidity of the sample.
    • Ratio Turbidimeter: Ratio turbidimeters operate based on the ratio of scattered light at two different angles. By measuring the ratio of scattered light intensities, these instruments can compensate for changes in particle size and color, providing a more accurate measurement of turbidity.
    • Infrared Turbidimeter: Infrared turbidimeters use infrared light sources and detectors to measure turbidity. They are particularly useful in applications where the sample may contain colored substances that interfere with measurements in the visible spectrum.
    • Laser Turbidimeter: Laser turbidimeters employ laser light sources to measure turbidity. They produce a highly focused beam of light, which allows for more precise measurements in low turbidity samples.
    • Portable Turbidimeter: Portable turbidity meters are handheld devices designed for field measurements. They are compact, battery-powered, and often equipped with a digital display for easy reading of turbidity values on-site.

    These are some of the commonly used types of turbidity meters. The selection of a particular type depends on factors such as the application, sample characteristics, required accuracy, and portability requirements.
