ETG - Model 6900 - Methane Gas Analyser for Emission Monitoring in Landfill
From Emission Monitoring
The ETG 6900 can reliably & selectively measure methane in low ppm concentrations without the need for frequent recalibrations. It is thus ideally suited for study on emission CH4 monitoring in landfill or remote-site applications, e.g. in environmental research.
Landfill Methane Emission Monitoring
Methane (CH4) plays a critical role in the radiation balance and chemistry of the atmosphere. The major anthropogenic sources are anaerobic production from landfills, ruminant animals and their waste, release from the mining and use of fossil fuel, burning of biomass, etc..
On average, over the global scale, landfill methane emissions contribute between 10-19% of the anthropogenic methane burden into the atmosphere.
CH4 is a potent greenhouse gas - about 25 times stronger than CO and outgases from reservoirs, landfills and permafrost soils.
The ETG 6900 can reliably & selectively measure methane in low ppm concentrations without the need for frequent recalibrations.
It is thus ideally suited for study on emission CH4 monitoring in landfill or remote-site applications, e.g. in environmental research.

ETG uses a technology-enhanced TDLS for gas detection, where 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.
ETG 6900 thus present a clear alternative to current sub-optimal detection solutions and combine precise, contact-less optical measurements with high target gas selectivity, calibration-free operation, low-cost-of-ownership
The program will displays graph, in real-time measurement. The origin of the axis time is made to coincide with the beginning of the measurement session. You will see real time data in the upper side of the window ('Last Measure'). In the same screen of the software indicates the presence of any alarms with a reference code (that's need to be communicated to ETG for troubleshooting)
