About Sulphur Dioxide SO2

Explosion proof Sulphur Dioxide ppm detector with display, alarm, flasher, ATEX, FM, UL certified

Sulfur dioxide SO2, is highly toxic gas. It is responsible for the smell of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of the burning of fossil fuels contaminated with sulfur compounds and copper extraction.
