We are very excited to announce that Gasmet’s new Mercury monitoring solution CMM AutoQAL has now launched! As the name might suggest, this robust Continuous Mercury Monitoring system comes with a test gas generator including automatic EN 15267 certified QAL3 validation tool. The validation tool is for HgCl2 span checks according to the EU Standard EN 14181. Being a TÜV certified solution (MCERTS certification pending) with an integrated and automatic QAL3 validation tool, this is a truly unique CMM solution on the market. Read on to find out what else the CMM AutoQAL is all about.

Continuous Mercury Monitoring Ensures Better Health and Safety

Mercury is a naturally-occuring compound, which in itself doesn’t pose a threat to the environment. It only becomes harmful to humans and other living organisms when released in the atmosphere and water via industrial emissions, for example. 

It is therefore vital that industrial plants such as large combustion plants and waste incineration plants that monitor their Hg emissions on a continuous basis. Continuous Mercury Monitoring is the most efficient way to prevent occupational and environmental hazards caused by airborne Hg.

Gasmet Continuous Mercury Monitoring Systems: An Overview

Gasmet offers two solutions for Continuous Mercury Monitoring (CMM):

  • CMM 
  • CMM AutoQAL

Both systems offer TÜV and MCERTS certified solutions that are ideal for measuring mercury continuously from hot, wet and corrosive gas streams. Gasmet CMM and CMM AutoQAL have the lowest EN 15267 certified ranges in the world (0-5 µg/m3). 

Thanks to the robust design and low detection limits, both continuous mercury monitoring systems are an excellent option for a wide range of demanding applications, such as:

  • Waste incineration
  • Power industry
  • Cement industry
  • Research

CMM and CMM AutoQAL Use CVAF Technology

The CMM and CMM AutoQAL utilize the CVAF (Cold Vapor Atomic Fluorescence) technology. It is an extremely sensitive and selective measurement principle for the measurement of trace mercury levels. 


This technology offers superior sensitivity and reduced cross-interference effects thanks to the very specific nature of the fluorescence effect. This is a particular advantage in applications where the concentration of mercury is low and the concentration of other UV absorbing gases such as SO2 is high. 

CMM AutoQAL: New Features

How do these robust and reliable systems differ? First of all, the new CMM AutoQAL now includes an automatic EN 15267 certified QAL3 validation tool for HgCl2 span checks according to the EU Standard EN 14181. This leads to savings in time and money, making the system the most cost efficient solution in the market.

The QAL3 equipment is an integrated part of the system and performs the automatic QAL3 validation checks quickly and easily without any additional costs or manual work. 

The Key Benefits of CMM AutoQAL Are:

  • Fast and easy QAL3 function with immediate pass/fail results
  • No need for additional equipment or third party services to perform QAL3 checks
  • Avoid laborious, time consuming and expensive QAL3 checks
  • No need to connect or disconnect additional equipment or hardware
  • Automatic QAL3 function ensures minimum downtime in emission reporting
  • Unique solution in the market, there’s no other similar solution currently available:

    CMM AutoQAL is the only TÜV certified solution (MCERTS pending) with fully integrated and automatic QAL3 validation tool in the market. We can proudly state that it is therefore a truly unique solution with nothing quite like it currently available for Continuous Mercury Monitoring.

CMM AutoQAL Answers to the Changing Emissions Monitoring Needs

In today’s world that needs rapid changes towards better environmental and social sustainability, good compliance with the emission standards and legislation is essential. It is therefore vital that industrial plants have the required equipment and tools to comply with these legislations and emission monitoring standards, such as the EN 14181 and EN 15267. In addition to emission limit compliance, industrial plants need to ensure that their continuous emissions monitoring equipment fulfil the required standards. 

Gasmet CMM is fully EN 15267 certified by MCERTS and TÜV. CMM AutoQAL is TÜV certified with a pending MCERTS certification status. 

Our future proof CMM systems have the highest sensitivity in the market. Thanks to our local technical service and support you can ensure that your monitoring system is performing securely and faultlessly 24/7.
