SO2 is a toxic gas with the distinct smell of burnt matches. Affecting the respiratory system, particularly lung function, and is an eye irritant. Sulfur dioxide irritates the respiratory tract and increases the risk of infections.

Burning fossil fuels including coal, oil, and natural gas can generate the harmful gas known as SO2. It is highly corrosive and has a pungent smell. Long-term exposure to high SO2 concentrations can harm the lungs and result in respiratory problems.

The need for reliable gas detection is vital for worker safety. Our Calibration gas is used to confirm the effectiveness of personal and static gas detection instrumentation in many industries.

Our SO2 calibration gas is manufactured to varying concentrations and combined with different balance gases to meet the different needs of each industry.
