O2T - flue gas tester for O2
Flue gas tester for O2
Oxygen measurement directly in the flue gas
Outputssignale for O2-content and flue gas temperature
The flue gas analyser O2T is a transducer for measuring the oxygen content and temperature of the flue gas.
The transmitter operates with a zirconia probe for O2 determination and with a measuring resistor Pt100 for temperature measurement. It is installed directly into the flue gas duct. A gas treatment is not required.
