The new flue gas analyser 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.

• High-resolution graphic display - The measurement menus and measurement values are presented in detail and always well legible.
• Sensor monitoring - Integriated traffic light system which continuously monitors the sensor functionality.
• Stamp of approval - The flue gas analyzer testo 320 is TÜV-tested according to EN 50379, Parts 1-3
• Automatic zeroing of sensor - Automatic zeroing of the gas sensor in only 30 seconds after starting, which can be cancelled if not required.
• Lithium rechargeable battery - Operation with lithium rechargeable battery (1500 mAh) – no need to change battery, up to eight hours running time, charging via USB possible.
• Attachment - Integrated magnets for fast attachment to burner.
• Probe filter - Easy exchange of probe filter.
• Memory - Up to 500 measurement protocols can be stored and called up in the memory of the testo 320.
