HM-1400 TRX 2

Total Mercury Analyzer

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

NEWS: Now with newly certified lowest measuring range acc. to EN 15267 of 0 … 15 µg/m³ for large combustion plants.

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

(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
