Flue gas analyzer Sensonic 4000

Sensonic 4000

The flue gas analyzer Sensonic 4000 is designed especially for service technicians who are permanently employed in measuring emissions and carrying out adjustments on various burner and heating equipment. Using the optional NO and NO2 sensors it is possible to calculate NOx simply as the sum of NO and NO2. SO2 can also be measured if needed. All parts of the flue gas analyzer are designed for a long and trouble-free operation.

Two extra analog inputs allow the simultaneous measurement of a voltage or current signal and a temperature. This makes it ideally suited for measurements on district heating plants. Manufactured with EN50379 in mind.
