Definition and Application of Water Quality Sensors What is a Water Quality Sensor? A water quality sensor is an advanced device designed to measure various parameters of water quality, including temperature, pH, dissolved oxygen, conductivity, turbidity, and the presence of pollutants such as heavy metals and chemicals. These sensors provide critical data about water quality,…
Five Detection Methods and Principles of COD What is COD? Chemical Oxygen Demand (COD), also known as chemical oxygen consumption, is a measure of the amount of oxygen required to oxidize organic and inorganic matter in water using a chemical oxidant such as potassium permanganate. COD is a critical parameter indicating the level of water…
Introduction to the Principles of Dissolved Oxygen Sensors I. Basic Concept of Dissolved Oxygen Sensors Dissolved oxygen (DO) refers to the amount of oxygen dissolved in water, expressed in milligrams of oxygen per liter of water (mg/L). DO exists in water as individual oxygen molecules. The concentration of dissolved oxygen is a crucial indicator of…
