A550® Handheld Combustion Analyser

O2, CO, CO High, NO

O2, CO, CO High, NO

Compact, robust and extremely accurate the A550® Handheld Combustion Analyser is all that is required to perform a complete analysis and inspection of small to medium combustion plants. The A550i is designed to be used in tough industrial heat processes. With its stainless steel sintered insitu filter and built in Peltier cooler, the A550i fits the requirements of the most demanding applications with high moisture content and heavy dust loads.

The individual functions can be launched as intuitively as using a smartphone via the large 7″ color touchscreen. And the brightly lit monitor can be read anywhere. The large screen, the clear arrangement and the graphical presentation of readings allow excellent readability . Smart handling features Acquiring measurement values is as easy as could be. The analyzer is equipped with magnets, so you can attach it to any magnetic objects to work hands-free. The probe is equipped with a start/stop button to run or hold measurement readings.

There are a generous number of interfaces available to transfer data: USB, infrared and Bluetooth®. The A550® Handheld Combustion Analyser with Bluetooth® feature can be used with the Wöhler A 550 APP INT for Android smartphones or tablets. For communication with computers and notebooks Wöhler offers a professional software program. Printing out the results on site is possible with the Wöhler
TD 100 Thermal Fast Printer.

A550® Handheld Combustion Analyser

Tailored to TODAY’s industrial requirements

Typical Applications

Boilers and burners commissioning, regulatory inspection, combustion control, process gas and emissions monitoring in combustion plants and associated filtration systems are typical applications for the A550® Handheld Combustion Analyser.

Emissions testing and regulatory inspections

Small and medium installations of combustion: gas burners, heating systems…

Large combustion plants: In coal and gas fired power stations, cement kiln, foundry, paper mills… Stringent regulatory requirements for emission monitoring and reporting.

The A550® Handheld Combustion Analyser enables efficient and flawlessly compliance for a large range of contaminants.

Gas Treatment Centres

Accuracy and high reliability in harsh conditions of operations makes the A550® Handheld Combustion Analyser a powerful optimisation tool for small to medium size installation of combustion.

SCR and SNCR Selective non-catalytic and catalytic reductions are designed to reduce the emissions of NOx by injecting ammonia is directly injected at the combustion chamber exhaust. This process causes the nitrogen oxides to react with the ammonium and turn into nitrogen and water. The A550® Handheld Combustion Analyser is suited to upstream and downstream SNCR/SCR short term testing and provides plants operator with accurate data to control the filtration process while optimising the combustion with upstream CO and O2 measurements.

GTC and flue gas scrubbers reduce the emissions of acid gases such as SO2 with pulverised lime powder or solutions while the discharge of heavy metals and organic pollutants is controlled with the addition of activated carbon. Accurate monitoring of O2, SO2 upstream of the GTC allows reducing the quantity of reagents injected.

Wohler Measuring Instruments

Wohler analysers and testing instruments are a byword for quality and just what you need to analyse and test heating systems, flue gas systems, ventilation systems and buildings.
