FAQ - SO2 Sensor
Why use the SO2 sensor?
Sulfur dioxide gas (SO2) is a toxic gas with a strong pungent smell. It exists in the atmosphere in very low concentrations and is naturally released during volcanic eruptions. Inhalation of sulfur dioxide is related to respiratory diseases and breathing difficulties. It is also a precursor to acid rain and atmospheric particulate matter. Sulfur dioxide gas can be an active ingredient or waste from several different industrial processes.
Where to use the sulfur dioxide sensor?
Sulfur dioxide sensor application range: environmental protection industry, cement plant; chemical industry, metallurgy, electric power; sulfuric acid manufacturing plant, pharmaceutical plant, food processing, etc.
What is the working principle of the sulfur dioxide sensor?
Our so2 sensor uses electrochemical principles, a three-electrode electrochemical sensor.
What are the types of So2 sensors?
Our so2 sensor uses electrochemical principles, a three-electrode electrochemical sensor.
