317-1 Flue Gas Leak Detector, Analyzer.
Electronic Dew Mirror For The Detection Of Leaking Flue Gases.
The electronic dew mirror quickly and efficiently detects escaping heating flue gases. 
Depending on the type of gas burner, flue gases may escape as a result of dirt or 
restrictions in the flue gas paths caused by e.g. wear in the nozzles, under loading or 
overloading of burner, material fatigue. There must be a functional fault if gas escapes from the burner and the presence of CO must be assumed.

The blockage in the flue is detected by the 
Testo 317-1 electronic dew mirror, 
an audible and visual alarm is triggered. 
The flexible probe is particularly suitable for 
areas which are difficult to access for 
checking purposes.

Applications:

• Detects whether flue gases are properly 
  vented from a burner in many situations.
