Overview As a high-precision water quality monitoring device, the signal detection process of fluorescent dissolved oxygen sensor involves knowledge and technology in multiple fields such as optics, electronics and signal processing. This article will introduce the signal detection process of fluorescent dissolved oxygen sensor in detail, including the generation and irradiation of excitation light, the generation and emission of fluorescence, the detection and signal conversion of...

Requirements for Turbidity Measurement Equipment Turbidity measurement places certain demands on equipment, focusing on performance, accuracy, stability, ease of operation, and other aspects. Below is a detailed explanation of the requirements for turbidity measurement equipment. Performance Requirements Measurement Range: Turbidity measurement equipment should have a wide measurement range to accommodate the measurement needs of different turbidity water bodies. The common measurement range is...

Water is the source of life, and its quality directly affects human health and the environment. Monitoring water quality is essential, and turbidity is one of the key indicators in this field. What is Turbidity? Turbidity, measured in NTU (Nephelometric Turbidity Units) or TU (Turbidity Units), is the degree of light scattering caused by suspended particles in water. These particles include silt, sand, microorganisms, plankton, and colloidal substances. Besides the concentration of suspended...

Overview of pH pH generally refers to the hydrogen ion concentration index. Hydrogen ion concentration is a method of expressing hydrogen ion concentration. It is the negative value of the common logarithm of the hydrogen ion concentration (activity) in aqueous solution, that is, -lg[H?]. The determination of hydrogen ion activity index can be qualitatively determined by using pH indicators and pH test paper, while quantitative pH measurement requires the use of pH analyzers or pH meters....
