About those infrared thermometers: They are fantastic, but... Please note that they sense reflected/radiated heat, from the surface you point them at. That surface is what reflects/radiates the heat. For example, a flat black surface will reflect/radiate heat more readily than will a white surface. A flat surface will reflect better than a rough or angular surface. This can fool you if you are not careful. Move it around a bit, and take the highest reading you can get out of it as the closest to what is the actual heat. Many people get fooled by this issue... (I use one on HVAC systems, and generally spray some flat black paint on whatever I'm checking, or apply black tape. Makes a huge difference sometimes.)
