SEC Probe

Permeation-based gas sampling system

Exclusive sampling system with no loss of condensable gases



  • Municipal waste incinerators
  • Hazardous waste incinerators
  • Combustion plants
  • Petrochemical industries
  • Cement plants
  • Glass industries
  • Paper mills


  • Sampling probe equipped with double stage particulate filtration
  • Permeation-based drying system (no condenser), avoiding the loss of highly soluble gases such as HCl, SO2 and NO2
  • Direct span gas injection to the probe made possible
  • Automatic backflush for reduced maintenance
  • Clean and dry sample transferred via unheated polytube at ambient air temperature up to 100 m distance
  • Large selection of probes available depending on the process conditions (stack diameter, gas temperature, water content, particulates concentration)
  • Optional built-in temperature and velocity sensors (no additional flange)
