Our robust combustion analyzers offer a lot of functions while being handy and easy-to-use. With Wohler analyzers, users can take care of any heating system. Heating systems should be tested every few years and more often when they are in use for a longer time. In some countries, there are even laws regulating this. Wohler combustion analyzers have several pumps for a valid and reliable measurement result. Among our systems, the Wohler A 450 system offers a large 5" color display. It can be bought in a standard or advanced set. The A 450 combustion analyzer comes in a nice-looking design and is handy. Of course, it is operated by a touch screen and is simple to use.
