The new graphic display in color, the testo 330 LL POC analyzer shows self-explanatory  graphics and icons easy to understand and clear presentations which greatly facilitate the interpretation of measurement data analysis of combustion products. The graphical presentation of data helps the user to move quickly and safely through the various measurements during the course of the analysis of a heating system. What until now was done by interpreting the meaning of numerical values ​​is now done much more easily, for example, symbols above or below  indicate if the heating system has been set correctly.

The testo 330 LL also features new menus that facilitate the analysis of the heating system, for example the menu for Measurement of Solid Fuels or the menu for Tightness Test. Directly connecting the set for the tightness test the testo 330 LL can carry out all relevant checks on the installation, so that no other instrument is needed, since the new range testo 330 has the tightness test included.
