As robust as cast iron, but as easy to operate as a smartphone – that's what Wohler's new A550WP flue gas analyzer feels like in your hand. Appropriately, the advantages are equally substantial: A tip with your finger on the Wohler A 550 WP 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 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 you can attach it to the casing of the heater or boiler – and your hands are 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-WP also comes with the TD 100 Thermal printer, Air temperature probe, and clamping cone.
