The Wohler A550L WP KIT (7754) Flue Gas Analyzer with TD 100 Thermal Fast Printer offers a touchscreen interface to quickly perform analyses, inspections, and settings on residential and commercial appliances, as well as visual displays of data to share with customers. 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 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-L-WP also comes with the TD 100 Thermal printer.
