one.Self-cleaning Turbidity Sensor working principle
Self-cleaning Turbidity Sensor comes with an automatic brush to eliminate air bubbles and reduce the impact of contamination on measurements, providing excellent stability even for long-term monitoring.The Self-cleaning Turbidity Sensor determines the concentration of particles in a liquid by measuring the scattering of light.It uses a light source to shine into a liquid and then measures the scattered light intensity at different angles.This sensor uses the 90° angle scattered light method to linearly process the collected values, and outputs turbidity values through a temperature compensation algorithm.

Four.Self-cleaning Turbidity Sensor care and maintenance
Sensor maintenance:
If the sensor needs to be cleaned, use warm water and an appropriate amount of detergent to clean it.
Notice:
Avoid strong vibrations that may damage the transparent glass in front of the ring, and do not scratch it with hard objects.
Oxidation-Reduction Potential, namely ORP, reflects the difference in the oxidation-reduction potential between the indicating electrode and the reference electrode in a liquid, and it can provide a comprehensive assessment of the oxidation-reduction state of the entire system. In a wastewater treat...
After an earthquake, aftershocks often occur. An aftershock is a small earthquake that occurs successively after the main shock. It is generated because when the main shock occurs, the rock layers in the earth's crust are strongly impacted, and the internal stress distribution changes greatly. T...
Soil moisture is the water in the soil. Quick and accurate measurement of soil moisture is important for farm management. Since the middle of the last century, people have been using a variety of methods to measure soil moisture, such as the drying method, the dielectric class method, the neutron me...
Air quality is an indicator that measures the content of pollutants in the air of a region. It is directly related to people's health and the sustainability of the environment. The quality of air is usually evaluated by monitoring the concentration of pollutants in the air. These pollutants may...
