Overview

  • Continuous mercury measurement
  • Measuring principle allows specification of elemental and oxidised mercury
  • Automatic reference point check with internal HgCl2 reference gas generator
  • No extremely heated components, easy to maintain
  • Smallest certified measuring range 0…15 µg/m3
  • QAL1 certified according to EN 15267

    Your Benefit

    • QAL1 certified according to EN 15267
      Type approved according to EN 15267-1, EN 15267-2, EN 15267-3 and EN 14181
    • Continuous measurement
      HM-1400 TRX 2 allows real-time monitoring of Hg emissions and is therefor suitable for process control and process optimization
    • Gas extraction with vacuum pump
      No expensive instrument air preparation for gas extraction required
    • No extremely heated components, easy to maintain
      The HM-1400 TRX 2 does not contain any extremely heated components and is thereby easy to maintain
    • Measuring principle allows Hg speciation
      The Speciation results immediately demonstrate and validate Hg reduction strategies and technologies or effect of alternative fuels
    • Remote access
      Remote monitoring (off-site and/or through plant control systems) results in minimized technician

    Applications

    • power industry (coal-fired power plants)
    • waste incineration (municipal waste, hazardous waste, sewage sludge)
    • cement industry
    • steel industry (steelworks with scrap metal reconditioning
    • fluorescent light bulb recycling

    (1)Variants / Options
    (2)The HM-1400 TRX 2 extracts sample from the process, removes H2O by condensation inside a cooler and standardizes the result with respect to T and p.
    (3)If the stack gas temperature is < 200°C then a heated sample tube is recommended, because the species HgCl2 is absorbed by surfaces with T < 140°C.
