Hi, Werner
I did not know that ovens generate IR. Would that be true of large
reflow ovens also, I mean even those that are fully convective?

Hi Richard,
The reason you are getting a lower reading for TC's in the air is that
you are also getting some infrared radiation heat transfer and the
absorptivity of anything plastic is much higher than that of a metallic
object {they are closer to being a 'Black Body']
