Uncertainties associated with the use of opacity meters (smoke meters)

  1. Sep 21, 2011 #1
    Please, I need practical instruction/calculation to find the uncertainty associated with the use of opacity meters (smoke meters). I cannot even start to calculate; I cannot find anything on this topic.
    Thx a lot.

    The uncertainty? What do you mean?

    Well, I need to calculate uncertainty by using statistical methods, which I generally have. But I need influencing factors which are contributing to mentioned uncertainty, for instrument called opacity meter (smoke meter).
    That instrument measures, if smoke at car exhaust (for diesel cars only) is too thick, literally.
    Practical model of calculation would be perfect, if someone have it.

    Thanks for every effort to help me.
    Best regards.
