Brief description of cross-interference

CO, H2, NO2 have very little interference; SO2, NO will cause a small positive interference; high humidity and organic vapors will accelerate aging, suitable for industrial high-concentration sulfur dioxide working conditions.

Typical applications

Oil and gas extraction, sewer / sewage tank, biogas project, desulfurization tower, refining and chemical industry, mining, replacement of portable / online H2S detection instrument spare parts
