Online turbidity meter is an instrument used to measure the concentration of suspended particles in water samples. It is widely used in environmental monitoring, water treatment, pharmaceuticals, food and other fields. However, the turbidity analyzer measurement results can be affected by a variety of factors. This article will analyze and discuss the factors that affect the measurement of the online turbidity meter.

1. Water quality characteristics

Type and concentration of suspended particles: Turbidity analyzers mainly measure the concentration of suspended particles in water samples, so the type and concentration of particles have a direct impact on the measurement results. Different types of particles may scatter and absorb light differently, thus affecting the measurement of turbidity values.

Particle Size and Shape: The size and shape of particles can also affect turbidity measurements. Generally speaking, larger particles are more likely to cause light scattering, thereby increasing turbidity values. The shape of particles, such as spheres, rods, etc., will also have different effects on scattered light.

2. Environmental factors

Temperature: Changes in water temperature will affect the motion state and optical properties of particles, thereby affecting turbidity measurements. Generally speaking, as the temperature increases, the movement of particles accelerates, which may lead to an increase in turbidity values.

Pressure: In underwater or deep-sea environments, changes in water pressure can have an impact on turbidity measurements. Changes in pressure may affect the settling velocity and optical properties of the particles, thereby affecting turbidity values.

3. Instrument factors

Light source: the digital online turbidity metertypically use a light source to emit light to measure turbidity. Factors such as the stability, wavelength and intensity of the light source may affect the measurement results. For example, changes in light source intensity may cause instability in turbidity values.

Detector: The detector is used to receive light scattered by water samples and convert it into electrical signals. Detector sensitivity and stability are critical to turbidity measurements. If the detector is faulty or unstable, this can lead to skewed measurement results.

Optical system: The optical system of the turbidity analyzer includes optical paths, lenses, filters and other components. Factors such as the quality, cleanliness and adjustment accuracy of these components can affect turbidity measurements. For example, dust or impurities in the optical path may cause light scattering, affecting measurement results.

4. Operation factors

Operator proficiency: Operator proficiency has an important impact on turbidity measurement results. Incorrect operating methods may lead to errors. Therefore, when using a online turbidity meter, you need to follow the operating procedures to ensure accurate operation.

Sample handling: Sample handling may have an impact on turbidity measurements. For example, processes such as sampling, storage, and dilution may cause particulate matter to settle, aggregate, or dissolve, thereby affecting turbidity values.

5. Summary

The measurement results of the turbidity analyzer are affected by many factors, including water quality characteristics, environmental factors, instrument factors and operational factors. In order to ensure the accuracy and reliability of the measurement results, it is necessary to fully consider the impact of these factors and take appropriate measures for control and correction. For example, calibrate and maintain the online turbidity meter regularly to keep the optical system clean and stable; follow procedures during operation to ensure the accuracy of sample processing and analysis; at the same time, monitor and record water quality characteristics and environmental factors, In order to analyze and evaluate the measurement results.
