Sulfur Dioxide (SO2) Detection

Portable & fixed-point SO2 detectors for healthcare, pharmaceuticals, chemical manufacturing, agriculture, and environmental testing.

About Sulfur Dioxide Detection

Sulfur Dioxide, a toxic gas with a pungent, irritating smell, is primarily produced by volcanic activity and as a byproduct of burning fossil fuels.

It has applications in the chemical industry as a preservative, in the production of sulfuric acid, and as a bleaching agent. The wine industry also uses it for its antioxidant and antibacterial properties. SO2’s potential to form acid rain and its respiratory hazards necessitate strict regulatory compliance and monitoring in the workplace.

Common Challenges

  • Accurate detection at low concentration levels
  • Ensuring continuous monitoring in varied environmental conditions
  • Mitigating false alarms caused by interference from other gases

Current Guidelines

OSHA:

  • PEL-TWA: 5 ppm (13 mg/m³)

NIOSH:

  • REL-STEL: 5 ppm (13 mg/m³)
