PORTABLE FLUE GAS ANALYZER WITH SUPERIOR ACCURACY
No matter how you look at it, the new Wöhler A 550 INDUSTRIAL really is a „nifty piece of equipment“: The individual functions can be launched as intuitively as using a smartphone via the large 7″ color touchscreen. And the brightly lit monitor can be read anywhere. The large screen, the clear arrangement and the graphical presentation of readings allow excellent readability.
