  Testo 320
  Just a few "clicks" away from a heating system diagnosis.
  testo 320. The highly efficient flue gas Analyser.
  The new testo 320 is the multi-function instrument for efficient flue gas analysis. It is convenient to operate and solves every task on a heating system. It offers numerous clearly structured measurement menus. Standardized menu procedures and a high-resolution colour display which presents the measurement results graphically, enable fast workflows. 500 measurement values can be stored in the instrument. A large selection of probes make the testo 320 flexible and further measuring instruments unnecessary.
  TV-tested according to EN 50379, Parts 1-3.    
 
 
Testo 320 is Most efficient flue gas analyser
Testo 320 specifications High-resolution graphic display
The measurement menus and measurement values are detailed and always legible.
Sensor monitoring
Integrated traffic light system for sensor functionality.
Stamp of approval
The testo 320 is TV-tested according to EN 50379, Parts 1-3.
Automatic zeroing of sensor
Automatic zeroing of the gas sensor in only 30 seconds.
Lithium rechargeable battery
Operation with lithium rechargeable battery (1500 mAh) up to 8 hours running time.
Attachment of the measuring instrument
Integrated magnets for easy fixing to burner.
Probe filter
Easy exchange of probe filter.
Flue gas measurement
The testo 320 directly measures CO and O 2, and additionally ambient and flue gas temperature.
Draught measurement
This allows the negative pressure in the heating system to be quickly determined.
Differential pressure measurement
With the differential pressure measurement, you monitor the gas supply on gas boilers quickly and easily.
Gas leak detection/gas pipe test
This accessory makes additional measuring instruments for these measurements unnecessary.
Ambient CO measurement
With the ambient CO probe, this measurement is possible parallel to the flue gas measurement.
Differential temperature measurement
With the differential temperature menu, you efficiently measure the discrepancy between the flow and return.
