China so2 gas sensor principle and application
The Sulfur Dioxide Gas Sensor FS02001 produced by Fosensor is a gas sensor based on the principle of electrochemical reaction and uses the electrochemical redox reaction of sulfur dioxide to measure the concentration of sulfur dioxide. Electrochemical sulfur dioxide sensors have the advantages of fast response, high sensitivity, and good stability, and are widely used in environmental monitoring, industrial safety and other fields.
Working principle of electrochemical China so2 gas sensor
The basic structure of the electrochemical China so2 gas sensor consists of working electrode, reference electrode, ion exchange membrane and electrolyte. The working electrode usually uses a platinum electrode, and the reference electrode usually uses a silver/silver chloride electrode. Ion exchange membrane is a membrane that selectively transmits sulfur dioxide and can prevent the influence of other interfering gases. The electrolyte usually uses acidic solutions such as hydrochloric acid or sulfuric acid.
When sulfur dioxide gas reaches the working electrode through the ion exchange membrane, an electrochemical oxidation reaction occurs, producing electrons and sulfate ions. These electrons flow in the external circuit, creating an electric current. The magnitude of the current is proportional to the concentration of sulfur dioxide.
Application of China so2 gas sensor
China so2 gas sensor is widely used in environmental monitoring, industrial safety and other fields.
Environmental monitoring
Chinese electrochemical sulfur dioxide sensors can be used to monitor sulfur dioxide concentrations in the atmosphere. Sulfur dioxide is an important atmospheric pollutant that can cause harm to human health and the ecological environment. Electrochemical sulfur dioxide sensors can quickly and accurately detect sulfur dioxide concentrations in the atmosphere, providing important data for environmental protection.
industrial safety
Electrochemical sulfur dioxide sensors can be used to monitor sulfur dioxide concentrations in industrial production processes. Sulfur dioxide is a by-product of many industrial processes and can pose a health hazard to workers. Electrochemical sulfur dioxide sensors can monitor sulfur dioxide concentration in industrial production processes in real time, providing safety assurance for workers.
