By default, 0.6m long wire is provided. Customers can extend the wire or connect the wire in sequence according to their needs.
Note that there is no yellow line in the line sequence that may be provided in some factory batches. In this case, the gray line is equivalent to the yellow line.
Why use SO2 sensors?
Sulfur dioxide gas (SO2) is a poisonous gas with strong pungent odor. It exists in the atmosphere in very low concentrations and is released naturally during volcanic eruptions. Sulphur dioxide inhalation has been linked to respiratory illness and breathing difficulties. It is also a precursor to acid rain and atmospheric particulate matter. Sulfur dioxide gas can be an active ingredient or a waste product from a number of different industrial processes.
Where is the sulfur dioxide sensor used?
Sulfur dioxide sensor application range: environmental protection industry, cement factory; Chemical industry, metallurgy, electric power; Sulfuric acid factory, pharmaceutical factory, food processing, etc.
How does the sulfur dioxide sensor work?
Our so2 sensor adopts electrochemical principle, three electrode electrochemical sensor.
