We must leave some thing for him self to learn! You are not helping by giving every thing to him!

I knew this very well! It was for him to learn then answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

A good teacher will guid the student with out telling him the answer, but giving him enough guestions to seek it out!

I have had impression that you are asking that question.

FYI I use a K type thermocouple and card board, I wouldn't trust any thing to an IR therm <_<

I use both, and sometimes PT1000 probes and Elliwell to read temperatures and every now and then I check my IR readings and I am very satisfied with precision (+-1K).
As you pointed above for teacher, check these terms in conjunction with IR temperature measurements:
1. Emissivity
2. Distance to spot ratio
