Gas Detection Q&A - For Your Safety Environments

Built-in advanced gas detector sensor and sound & light alarm to ensure precise and safe gas detection in hazardous applications.

Q: What is the normal concentration of SO2 in the air?

A: The normal concentration of Sulfur Dioxide (SO2) in the air varies depending on location and environmental factors. In unpolluted, clean air, SO2 concentrations typically range from 0.1 to 1.5 parts per billion (ppb) or even lower. However, in areas with industrial activity, urban pollution, or proximity to sources like volcanoes, SO2 levels can be significantly higher, ranging from a few ppb to several parts per million (ppm).

To monitor Sulfur Dioxide levels accurately and ensure safety, it's essential to use a reliable gas detector. Electrochemical sensors are commonly used for this purpose due to their sensitivity and selectivity. These sensors operate by measuring the electrical current generated during the oxidation of Sulfur Dioxide at an electrode.

When selecting a gas detector, consider your specific application, monitoring requirements, and the expected gas concentration range in your area to choose the most suitable device. Regular maintenance and calibration are essential to ensure accurate and reliable measurements.
