B. Intended purpose
This chapter describes the areas of application for which the measuring instrument is
intended.
The testo 330 is a handheld measuring device for the professional flue gas analysis of
furnace systems:
· Small furnaces (burning oil, gas, wood, coal)
· Low-temperature and condensing boilers
· Gas heaters
These systems can be adjusted using the testo 330 and checked for compliance with
the applicable limit values.
The measuring instrument is approved for measurements under the German regulations
on immissions protection (1. BImSchV).
The following tasks can also be carried out with the testo 330:
· Regulating the O

values in furnaces for the purpose of
ensuring optimal operation.
· Draught measurement.
· Measuring and regulating the gas flow pressure in gas heaters.
· Measuring and optimising the flow and return temperatures of heating systems.
· CO- and CO
