Hello. Today I want to talk about the all new Wohler A 450 Wireless Combustion Analyzer. For those who are unaware, Wohler is a German manufacturer that started in 1932 as chimney brush making factory in Berlin. In 1965 they started developing and producing their first measuring devices. Wohler may be a big player in the chimney sweeping business, their commitment to developing great combustion analyzers cannot be questioned.
