Case

As robust as cast iron, but as easy to operate as a smartphone – that's what Wohler's new flue gas analyzer feels like in your hand. Appropriately, the advantages are equally substantial: A tip with your finger on the Wohler 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).

No matter how you look at it, the new Wohler A 550 really is a "nifty piece of equipment": The individual functions can be called up as intuitively as using a smartphone via the large 7" color touchscreen. 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.

"Smart" handling features

Acquiring measurement values is as easy as could be. 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 interfaces available to transfer data to other management programs: USB, infrared and Bluetooth. And with the new Wohler TD 100 Fast Thermal Printer you can print out the readings on the spot, so the customer immediately has the values in black and white in their hand/

Benefits:

Simple to use: Switch on – read off – done
Large, color touchscreen: Displays up to 14 measurement and calculation values
Intuitive to operate via on-screen keyboard
Calibrate in the flue gas pipe via a fresh air pump (Wohler A 550)
Graphic hot spot search
