Please go and get a _simple_ thermocouple thermometer. It's even cheaper  
than the optical ones. You will be much happier with something that  
actually reads the temperature and not a random number.

Accept it, optical thermometers are just another useless but popular thing  
to sell to "the silly sheep" and no good for measuring a wide variety of  
surfaces.
