OVERVIEW & SPECIFICATION

The new flue gas analyzer testo 320 solves every

measurement task on a heating system. It offers

numerous measurement menus, for example for

flue gas, draught, differential pressure and ambient

CO measurement. The large selection of variable

probes makes the testo 320 even more

efficient.

You have everything you need for complex measurements

on heating systems in one instrument.

With the testo 320, you comply with all legal

guidelines, and measure on this basis.
