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).
