sensors are suitable for their own requirements. Sulfur Dioxide Gas Sensor SO2/C1 SO2 Gas Sensor in Compact Housing Key Features • Highly sensitive SO2 measurements Applications • Continuous Air Quality Monitoring • Safety and Environmental Control Measurement Operation Principle 3Electrode Electrochemical Nominal Range 0 1 ppm

• Sulfur Dioxide (SO2) Sensor: The SO2 contributes to acidification of soil and surface water. It causes damage to vegetation. SO2 sensor monitors SO2 levels. • Nitrogen Dioxide (NO2) sensor: It monitors NO 2 level. • Carbon Monoxide (CO) sensor: It monitors CO level. The CO reduces amount of oxygen reaching organs and tissues of human beings.

Nondispersive infrared sensors (NDIR) of the FLOW EVO series for SO 2 emission measurement are therefore the perfect choice. They combine excellent measuring precision with a compact and userfriendly design. The sensor of the FLOW EVO SO 2 series with an SO 2 measuring range of 2000 ppm features longterm stability, repeatability and reliability. Dualbeam technology ensures very low drift.
