Arthiir Grillo measuring & controlling systems Measurement accuracy - O2 measurement: Measuring accuracy - Temperature: Measuring accuracy of the transmitter: Operating Mode: □ 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.
