Smart environmental monitoring solutions
The MMS comprises a multiplexer-valve unit and a highly accurate and selective mercury detector (VM-3000 Vapor Monitor) for measurements in air and other gases
Each mercury on-line system will differ in sample characteristics as well as installation conditions and operating environment. We have the experience to design systems that fully meet the requirements of your particular mercury monitoring task.

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).
QAL 1 certified for continuous, accurate and reliable measurement of total mercury emissions, even in very low concentrations and within complex matrices (SO2, NOx, HCl, etc.) With over 20 years experience, Mercury Instruments (part of ENVEA Group) were the first to develop mercury monitors and mercury analyzers using a dry thermocatalytic method instead of wet chemistry. The SM-4 Mercury Monitor is QAL1 certified and is ready to meet future regulatory requirements (Minamata convention & European directives for thermal power plants and incinerators).
Beneficiary of over 20 years of experience in mercury measurement, the new SM-5 CEMS Hg analyzer is designed to provide extremely accurate and reliable continuous measurements of very low concentrations of Hg in flue gas emissions. The SM-5 features short response times, dynamic ranges and stable measurement under all circumstances.
The VM-3000 Mercury Vapor Monitor measures continuously the Hg concentration in air and other gases. It is used for laboratory applications as well as installed at places where mercury has to be monitored. It is a great tool for many different fields of applications in scientific research or the industrial sector

The AULA-254 Gold is a fully automated system for analyzing traces of mercury in aqueous and digested samples In contrast to a typical multi-element AAS the AULA is specially designed for mercury determination. The use of a highly stable low-pressure electrodeless mercury discharge lamp (EDL) in connection with the latest UV detector techniques result in excellent baseline stability and low detection limits. The AULA-254 Gold system meets current regulations, with capacity in reserve to meet more stringent standards.
