Flue gas analysers
Flue gas measuring instruments have been among Testo’s bestsellers for decades. 40 years ago, our flue gas analysers were heavy and bulky, but today they are compact and networked.
For every task on boilers
Testo’s engineers work continually on the ongoing development of measuring instruments for smoke gas analysis, because it is only by carrying out regular servicing with a suitable flue gas measuring instrument that heating systems can run efficiently, emissions be reduced and you work even more easily.
