Wöhler A 550 NO Combustion Analyzer

As robust as cast iron, but as easy to operate as a smartphone – that's what Wöhler's new flue gas analyzer feels like in your hand. Appropriately, the advantages are equally substantial: A tip with your finger on the Wöhler A 550 is all that is required to perform analyses, inspections and settings on residential and commercial appliances. The flue gas analyzer is equipped with coded connections for the 4 Pa test and even »NEW AND UNIQUE« a wood moisture content measurement function to VDI Guideline 4206 (VDI = Association of German Engineers).

In the past 50 plus years I have purchased or used a fast variety of analyzers for myself and the technicians that I employed. Looking back over that time most of the analyzers performed adequately for those times, my only regret is that I did not have a Wohler analyzer back then. I personally own a Wohler A550 analyzer which I use to demonstrate setup, maintenance, and diagnostic trouble shooting on live fire equipment… I hold an analyzer to a very high standard, as it is the most important piece of equipment that is carried in a service van.«
