Applications
Differential pressure measurement
You can use the testo 330i flue gas analyzer to check the gas supply on gas boilers. You can therefore measure gas flow pressure and gas resting pressure in order to ensure that the system can be commissioned. You can also use the data specified by the manufacturer for the nozzle pressure to tailor the appliance output to the heat requirement.
Flue gas analysis and flue gas measurement
The testo 330i is equipped with two long-life sensors for measuring O2 and CO and can optionally be upgraded with an NO sensor. Flue gas and draught are measured in parallel, so all relevant flue gas parameters are displayed simultaneously on the smartphone.
O2 supply air measurement
In balanced flue systems, you can use the testo 330i flue gas analyzer to check whether there is a leak in the flue gas system. Measure the O2 content of the combustion air in the dual wall clearance to ensure that no flue gas is getting into the combustion air supply, thus preventing damage due to condensate or impairment of the combustion process.
