Measurement / monitoring of atmospheric pollutants is carried out with complex, high performance, high precision and sensitivity analyzers, mounted in an autolaborator, and the values are displayed in real time:

  • Analyzer for NOx : chemiluminescent measurement principle, range 0-10pm, detectable lower limit: ≤0,5 ppb;
  • Analyzer for CO :the principle of measuring non-dissipative absorption in IR, range 0-10 ppm, detectable lower limit : ≤1 ppb
  • Analyzer for SO 2 : UV fluorescence measurement principle, range 0-10 ppm, detectable lower limit : ≤1 ppb
  • Analyzer for O 3 : the UV photometry measurement principle, the 0-10 ppm range, the detectable lower limit : ≤0,5 ppb
  • Analyzer for THC (total hydrocarbons), NMHC si CH 4 : FID measurement principle, range: 0-100 ppmC, detectable lower limit : ≤0,5 ppmC
  • Analyzer for powder PM10 : the principle of gravimetric measurement
Measurement / monitoring of emissions at the source is done with an automatic portable analyzer, which measures and displays the values ​​in real time:

  • NO x:chemiluminescent measurement principle, range 0-2500 ppm
  • SO 2, CO, CO 2: measurement principle non-dissipative absorption in IR, range: SO 2: 0-3000 ppm; CO: 0-5000 ppm; CO 2: 0-20% vol
  • O 2: Paramagnetic measurement principle, range: 0-25% vol
