Mô tả sản phẩm: Land-Stack Gas Emissions analyzer FGA 900 Series
Overview:
Range of Stack Gas Emissions Analysers
The FGA range of analyzers use dual sensor technology to measure the levels of Nitrogen Oxides, Carbon Monoxide and Oxygen in flue gas.
- O2
- CO
- NO
- NO2
- NOX
Key Features
- Fully integrated system in a single compact box - no additional components required
- Suitable for a wide range of applications - up to 3 gases in a single analyzer
- Low maintenance - straightforward servicing without specialist skills
- Proven high performance - dual sensor measurement technique, TÜV & MCerts approved/Certified to US EPA standards
- True measured Total NOx - separate NO + NO2 sensors for true NOx monitoring, no converters necessary
- Simple installation - locate the analyzer anywhere, including outside locations
- Automatic calibration option - for continuous unattended operation in compliance monitoring applications
- Combustion Efficiency measurement option - for optimizing process efficiency where conditions are changing
The FGA range of analyzers use dual sensor technology to measure the levels of Nitrogen Oxides, Carbon Monoxide and Oxygen in flue gas.
This range of gas analysers carry a wide range of compliance and performance approvals including those from the US-EPA, UK MCERTS and German TÜV.
Land’s measurement technique ensures stable long-term operation with high accuracy and very low drift. Engineered for ease of maintenance and packaged for the industrial environment, FGA series analyzers are simple to install and trouble-free in operation.
Measurement Capability
FGA 900 Series stack gas emissions analysers can measure up to 3 gases in a single instrument.
- Carbon Monoxide (CO)
- Oxygen(O2)
- Nitric Oxide (NO)
- Nitrogen Dioxide (NO2)
- Nitrogen Oxides (NOx)
- Carbon Dioxide (CO2) Calculated
Compact, Weatherproof Design
The FGA stack gas emissions analyser is very compact. The choice of installation location and access is therefore made much simpler. They are packaged in weatherproof cabinets, intended for mounting directly on to a convenient wall or structure, inside or outside.
True NOx Measurement
The analyzer measures both NO and NO2 separately, these are combined to give a true NOx measurement output. The inherent problems with catalytic NO2 converters are therefore completely avoided.
