Total Gaseous Mercury (TGM) ultratracer


Measuring of Total Gaseous Mercury (TGM) in air and other gases. Reliable for measurements at ultra-trace levels (sub-ng/m3) according to EN 15852.

The UT-3000 operates automatically. All functions are controlled by an embedded microprocessor. When measurements are carried out, all parameters and results are stored in the integrated data logger. 

With standard settings the data logger has a recording capacity of 5000 measurements (approx. 2 months).

  • Offers sensitivity and detection limits far superior to other mercury analyzers on the market using similar technologies
  • Unlike with the fluorescence detection method, the analyzer does not require expensive carrier gases
  • Insensitive to interferences caused by the quenching effect
  • Automatic Operation
  • Automatic sample flow control
  • AutoRange function
  • Manual or automatic calibration modules (optional accessories)
  • Integrated data logger for more than 5000 measurements
  • Multiplexer operation (option)
  • Special version UT-3000 NG mobile (option) – all in one system for mercury measurements in natural gas
  • Continuous outdoor and indoor air quality monitoring
  • Stationary and mobile AQMS laboratories
  • Industrial fence-line and field monitoring
  • Environmental pollution source tracking
  • Studies of mercury dispersion in the atmosphere
  • Natural gas and derivatives
  • Emission monitoring
  • Process monitoring
  • Plume profiling
  • Studies of interaction between atmosphere and surfaces
  • Soil and ground degassing studies
