New, Portable TDL Gas Analyser for HCl and NH3 Monitoring

Feb 21 2018 Read 1080 Times

HCl continuous emissions monitoring systems (CEMS) applications have been around for several years – starting primarily in the waste or trash incineration processes. The chlorines in the plastics that are burned in trash incinerators will combine with the moisture in the trash to form HCl during the combustion process.

Ammonia (NH3 ) emissions are also an important contributor to fine particulate matter (PM) formation. Consequently, increased attention is being paid to accurate quantification and characterization of NH3 emissions.

ETG’s new ETG 6900 P for HCl and ETG 6900 P for NH3 are reliable and portable devices for monitoring the content of HCl and NH3 in stack emissions, which can operate without any sample conditioning

ETG use the technology-enhanced TDLS for gas detection, in which a 0.1 nm narrow bandwidth diode laser beam is scanned across an absorption band of the target gas, performing a high-resolution near-infrared absorption measurement.

The Tunable Diode Laser Technology performs very rapid HCl and NH3 detection using a sample pump inside for a “hot” measurement . The instrument includes 3 metres of heated line and a stack probe with on line filter, so it is ready to operate immediately.

Monitor Touch Screen , Modbus, Profibus, Ethernet output , Ethernet and USB Remoting, Long Lifetime Laser (+10 years) are some of the features of the ETG 6900 P NH3 – HCl Portable Gas monitor.
