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. |
| (4) | For large combustion plants and waste incinerators |
