The Wohler A550 SO2 KIT (7765)Flue Gas Analyzer with NO/NO2/SO2, TD 100 Thermal Fast Printer is as robust as cast iron, but as easy to operate as a smartphone. The touchscreen makes it simple 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 a wood moisture content measurement function to VDI Guideline 4206. The individual functions can be called up as intuitively as using a smartphone via the large 7" color touch-screen. And the brightly lit monitor can be read anywhere. The generously dimensioned screen and the clearly arranged, in part graphic presentation of readings are an absolutely ideal basis for holding discussions with customers. The analyzer is equipped with magnets, so it can be attached to the casing of the heater or boiler – leaving hands free to work. The probe is fitted with an additional start/stop button, with which it is possible to start or stop measurement readings. There are a generous number of inter-faces available to transfer data to other management programs: USB, infrared and Bluetooth. The A-550-SO2 also comes with the TD 100 Thermal printer and a sensor for NO, NO2, and SO2 measurements as well as an air temperature probe, and clamping cone.
