   I  ​wonder about those IR thermometers so prevalent    
   during the past year.  Previously, I recall seeing them    
   at deli salad bars, used to monitor the sour tureens.   
      
   I understand the physics, the relationship between    
   spectrum and temperature. What is the accuracy,    
   considering the problems of focus and reflection,    
   and ambient noise?   
      
   What's the internal sensor?
