- Quick response: The sensor can measure and display the turbidity value in real time, which is convenient for timely monitoring of water quality changes.
- Wide application: Digital turbidity sensors are widely used in environmental protection, water quality monitoring, industrial production, food processing and other fields, and are one of the important tools for water quality testing.
Présentation du produit :
The digital turbidity sensor, also often called the digital turbidity sensor, is a precision instrument used to measure the concentration of suspended matter in water. It is based on optical principles and calculates the turbidity of water, i.e. turbidity, by measuring the scattering phenomenon of light when it passes through an aqueous solution.
This digital turbidity sensor uses an RS485 communication interface and standard Modbus protocol, comes with a cleaning brush, uses an infrared light source, is not affected by the chromaticity of the water sample, and uses a 90° scattering method, which is suitable for various harsh working environments.
Working principle: When light passes through a liquid containing suspended particles, part of the light will be reflected by the particles, and the other part of the light will penetrate the particles and reach the detector. According to the light scattering theory, the scattering intensity of light by particles is proportional to its concentration. Therefore, by measuring the intensity of reflected light and penetrating light (or the ratio of scattered light to transmitted light ), the concentration of particles, i.e. the turbidity of water, can be calculated.
Application:
Drinking water monitoring: ensure the cleanliness and safety of drinking water, monitor the turbidity of water sources, water plant outlets and pipe network end water.
Industrial wastewater treatment: During the wastewater treatment process, monitor the turbidity of the wastewater to evaluate the treatment effect. Control the treatment process to ensure that the wastewater discharge meets environmental protection standards.
Environmental monitoring station: As one of the important equipment of the environmental monitoring station, it is used to monitor the turbidity of environmental water bodies in real time and provide data support for environmental protection and pollution control.
