Flue Gas Measurement: The testo 320 directly measures CO and O2 , and additionally ambient and flue gas temperature. From these values, and dependent on fuel-specific parameters, the instrument automatically calculates all other measurement parameters such as CO2 concentration, degree of effectivity and flue gas loss. This provides graphically prepared information on whether the heating system is working efficiently or whether there is a need for optimization.
Gas Leak Detection: The gas leak probe makes an additional measuring instrument, which you would otherwise need, unnecessary. It allows you to safely identify gas leaks on pipelines. The measurement result can be stored and documented, and if required presented to the customer. The display is shown in ppm.
Draught Measurement: Draught measurement ensures that the flue gas is correctly drawn off through the flue. This measurement menu is specially intended for checking the respective negative pressure of the heating system. In addition to this the current and maximum flue gas temperature is displayed.
