With the Testo 330-2 LX anniversary set, you are equipped for the most important measurements involving heating systems: The TÜV-tested flue gas analyser testo 330-2 LX is delivered with an O2 and a CO H2-compensated sensor, TÜV-tested modular flue gas probe, system case and practical accessories.

The great adavantage of this flue gas analyser is its capability for dialogue. At the press of a button, the instrument diagnosis provides information on qualitiative status, e.g. the filling level of the condensate trap, or of wearing parts such as the status of the gas sensors. Maintenance intervals are also displayed.


5-year warranty without maintenance contract on O2 and CO sensors.
Bluetooth Interface with free App for operation and documentation.
testo 330-2 LX flue gas analyser with fresh air valve to protect the CO measuring cell and to extend the CO measuring range to 30,000 ppm.
Single-hose connection: just one hand movement is needed to securely connect all the channels for flue gas measurement (gas paths, draught, temperature probe integrated into the flue gas probe).
