General Information on SO2 – Sulfur dioxide
General Information on SO2
Sulfur dioxide (SO2) is a colorless, mucous membrane-irritating, pungent-smelling and sour-tasting toxic gas. It is very soluble in water and forms sulfurous acid with water to a very small extent. It is formed, among other things, during the combustion of sulfur-containing fossil fuels such as coal or petroleum products. As a result, it contributes significantly to air pollution. Various processes exist for flue gas desulfurization. In addition, sulfur dioxide is found in the vicinity of active volcanoes.
Gas Sensors for the Detection of SO2
RITTER »MultiGas« Combined Modules NDIR + NDUV
RITTER »MultiGas« Modules can also be a combination of both NDIR sensors and NDUV sensors on a common board. With this unit, up to 3 gas components can be measured simultaneously. The basic electronics can supply IR and UV radiation sources with different frequencies for 0 Hz (DC) to 100 Hz (AC). This system is an ideal tool for detecting multi-component gas at low ppm levels.
Please note: For technical and chemical reasons, not every combination of gases/measuring ranges can be analyzed/measured in a single or combined RITTER »MultiGas« module. As this is a rather complex topic, please do not hesitate to contact one of our gas experts first.
