Monitoring with isokinetic samplers

We require industrial companies to sample some pollutants in chimneys and flues using isokinetic samplers. Isokinetic means the velocity of gas entering the sampler is the same as in the chimney or flue.

Many isokinetic samplers work automatically and must be approved under the MCERTS Automatic Isokinetic Samplers scheme. Two main types of equipment are covered:

  • automatic samplers used for dust and aerosol monitoring
  • continuous samplers used for long term dioxin monitoring
