Air and gas analysis
Measured / controlled parameters
Measurement of gas concentrations (O₂, CO, COlow, NO, NOlow, NO₂, SO₂, SO₂low, H₂S, CH₄, C₃H₈, C₄H₁₀, CO₂), velocity/volume flow, absolute and differential pressure, flue gas temperature, calculation of efficiency, losses, and dew point.
Measurement / analysis range
Depending on sensor: O₂: 0–25 Vol.%, CO₂ NDIR: 0–50 Vol.%, CO: 0–10,000 ppm, NO: 0–4000 ppm, NO₂: 0–500 ppm, SO₂: 0–5000 ppm, CH₄: 100–40,000 ppm, C₃H₈: 100–21,000 ppm, C₄H₁₀: 100–18,000 ppm, etc.
Measurement accuracy / precision
Depending on sensor: O₂ ±0.8 % f.s., CO₂ NDIR ±0.5 Vol.% + 1.5 % of reading, CO ±10 ppm (0–199 ppm) / ±5 % of reading (>200 ppm), etc.
