Interpretation of the principle and application of the turbidimeter

Author:QINSUN Released in:2023-05 Click:143

The turbidimeter has a built-in microprocessor with advanced configuration and powerful functions. It is a very precise turbidity measuring instrument. Based on the 880nm infrared light source passing through the optical lens and entering the sample liquid, the scattering in the 90° direction is measured according to the standard. Optical principle;

This analyzer can be used to measure the turbidity of raw water or pure water on filter devices in different places, such as drinking water, various production and industrial waters, and any need to use A place with qualified water.

The high-precision turbidimeter has a compact structure, built-in backlit LCD display, data memory and relay control output (3 channels).

This turbidimeter has powerful functions and is suitable for factories, fields and meven in laboratories. IP67 protection level, can perform rapid turbidity measurement, suitable for your various needs.

The range can be automatically adjusted between 0 and 1000 NTU, and the reading can be obtained in seconds. The large, bright display makes it easy to read and record measurement results, suitable for a variety of working environments.

Turbidity, i.e. the turbidity of water, is caused by traces of insoluble suspended solids and colloidal substances in water. Turbidity is measured with an instrument called a turbidimeter. A turbidimeter is a device for measuring the turbidity of water.

There are scattered light type, transmitted light type and transmitted scattered light type, etc., which are commonly called optical turbidity agents.

The principle is that when light strikes the surface of the liquid, there is a certaine correlation between the ratio of incident light intensity, transmitted light intensity and scattered light intensity and the turbidity of the water sample, by measuring the ratio of transmitted light to light intensity scattered and incident light intensity or transmitted light intensity at scattered light intensity to determine the turbidity of water samples.

The principle adopted is roughly as follows: a parallel beam of light propagates in a transparent liquid. If there are no suspended particles in the liquid, the beam will not change direction when traveling in a straight line;

If there are particles in suspension, the beam will change direction when it encounters the particles (whether the particles are transparent or not).

This forms the so-called scattered light. The more particles there are (high turbidity), the greater the light scattering.is important. A nephelometer sends light through a section of sample and measures the amount of light scattered by particles in the water at a 90° angle to the incident light.

This method of measuring scattered light is called the scattering method. All true turbidity should be measured this way. The turbidimeter is suitable for field and laboratory measurements, as well as 24-hour continuous monitoring.

Turbidimeters can be set to sound an alarm when measured turbidity values exceed safety standards.

Subject:

1. Drinking water: Determination of water quality turbidity by environmental protection department;

 2. Determination of industrial water: it can be used to understand the change in turbidity and the determination of the final turbidity value in the process of water treatment.ectrodialysis, ion exchange, ultrafiltration and other water treatments;

3. EBC turbidity test in the wine industry: determination of turbidity in the brewery;

4. Others: The turbidity tester can also be used in the pharmaceutical industry, epidemic prevention departments, hospitals, clinical laboratories and other Turbidimetry reagents and preparations .
