Zirconia probe is used for the continuous measurement of ______________ flue gases going out of the furnace?

Correct answer: A. Oxygen in

  • A. Oxygen in
  • B. Carbon dioxide in
  • C. Carbon monoxide in
  • D. Temperature of

Explanation

A zirconia probe measures oxygen by producing an electrical signal related to the oxygen partial-pressure difference across its electrolyte. It is therefore used for continuous oxygen analysis in furnace flue gases.
