1. Oxygen monitoring apparatus, comprising:

  • a flow component including;

    a flow passage; and

    a luminescable composition positioned so as to be exposed to gases flowing through said flow passage, luminescence of said luminescable composition being quenched when said luminescable composition is exposed to oxygen; and

    a transducer removably securable to said flow component and including;

    a radiation source which emits at least a wavelength of electromagnetic radiation capable of exciting said luminescable composition; and

    a detector configured to sense electromagnetic radiation of at least one wavelength emitted by said luminescable composition and to produce a signal indicative of an intensity of said at least one wavelength emitted by said luminescable composition, said detector being oriented, upon securing said transducer to said flow component, to receive electromagnetic radiation emitted by said luminescable composition.
