Total Gaseous Mercury (TGM) ultratracer

UT-3000

Mercury ultratracer measuring the Total Gaseous Mercury (TGM) in air and other gases. Compact and reliable for measurements at ultra-trace levels (sub-ng/m³) according to the 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 4 weeks.

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
