Total Gaseous Mercury Monitoring System [System 400Hg TGM(Opsis)]

Waste incinerators, cement plants and power plants need good and reliable measurements of total gaseous mercury.
The measurement of total gaseous mercury (TGM) is a challenge due to chemical reactions and contamination. The installed systems will often require a lot of maintanence still not giving reliable results. The OPSIS System 400Hg DOAS system is different and provides an accurate analyser that will operate with a minimum of maintanence. The OPSIS DOAS system is based on a non contact method using an optical path. For the measurement of total gaseous mercury, the gases will pass a dry catalytic converter before entering into the optical path.


  • Approved By TUV.
  • The system meets the European EN 15267 and other international standards.
  • Uses optical path and non contact method for determination of mercury
  • Requires less maintenance
  • Easy controls with clear digital display
  • Hassle free performance with longer functional life
  • Provides exact readings for regulation of gaseous mercury

Measuring Parameters:

  • NOx, SO2, CO, CO2, NH3, H2O, HF, and HCl
