HM-1400 TRX

Total mercury analyzer

Certified total mercury analyzer for continuous mercury monitoring in stack or process gases allowing speciation of elemental and ionic mercury.

 

 

 

Overview

  • continuous measurement
  • measurement principle allows Hg speciation
  • automatic reference point check with internal HgCl2 calibration gas generator
  • no extremely heated components, easy to maintain
  • QAL1 certified according to EN 15267
  • quick and easy exchange of reactor material
  • suitable for process measurement in raw gases
  • remote access option

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 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.
