HM-1400 TRX 2

Continuous Mercury Measurement in Stack or Process Gases

The HM-1400 TRX2 is a the most accurate analyser for continuous mercury measurement in stack or process gases allowing speciation of elemental and oxidised mercury.
The analyser is certified QAL1 according to EN 1567 and has an automatic reference point check with internal reference gas generator. This analyser has shown a great level of reliability in a wide range of applications such as power industry (coal-fired power plants), waste incineration (municipal waste, hazardous waste, sewage sludge), cement industry, steel industry (steelworks with scrap metal reconditioning) and fluorescent light bulb recycling.

Mercury Analyser

Exclusive Features
HM-1400 TRX 2

Continuous measurement

HM-1400 TRX 2 allows real-time monitoring of Hg emissions and is therefor suitable for process control and process optimisation. Also smallest certified measuring range 0…15 µg/m3*

 No extremely heated components and Easy to maintain

The HM-1400 TRX 2 does not contain any extremely heated components and includes a fast system cooling and is thereby easy to maintain. Maintenance interval every 3 months

Convenient operation

Remote monitoring (off-site and/or through plant control systems) results in minimised technician

Internal reference gas generator 

Automatic reference point check with internal HgCl2 reference gas generator

Smallest certified measuring range 0…15 µg/m3*

Stable measured values and maximum of daily
average values and suitable for daily average values <10 μg/m3

Measuring principle allows Hg speciation

The Speciation results immediately demonstrate and validate Hg reduction strategies and technologies or effect of alternative fuels

Cost savings 
due to process optimisation and reduced operational costs
Certified QAL1 according to EN 15267

Type approved according to EN 15267-1, EN 15267-2, EN 15267-3 and EN 14181

Stack Monitoring Solution

Industrial Stacks

With stricter environmental regulations optimisation of the combustion process for reduced pollutant emission and higher fuel efficiency is a major objective for manufacturers.

Monitoring solutions and applications for stack industries 

  • Oxygen concentration monitoring, in combustion flue gas to ensure fuel efficiency of the industrial burners.
  • Low dust concentration monitoring, to ensure continuous measure and control dust emissions to all stacks industries.

Continuous emission monitoring applicable for a wide range of applications, such as: 

    • incineration plants
    • waste incineration plants
    • power plants
    • Cement plants
    • metal industry
    • on plants according to 2001/80/EC LCPD
    • on plants according to IED 2010/75/EU
