Blackbody emissivity different to thermometers

  1. Oct 4, 2012 #1
    I am doing some research on thermometers and have a blackbody to test some infrared ones. Unfortunately the blackbody has an emissivity of 0.97 +/- 0.02 and the thermometer has an emissivity of approximately 0.96? How do I correct for the differences?

    I have had a quick look online and other forum questions but I haven't been able to find anything relevant as most say change the value on the thermometer but this is not possible in this case.

    I would be grateful of any advice or help as I want to make sure my calculations are correct.

    Thank you
