Re: Average temp ranges?
Thermal imaging camera...coool.
You can also purchase an infrared thermometer from a auto parts store for $20-30. These take the surface temperatures of wherever you point the little laser dot at (though with mine, the sweet spot is actually just above the dot). The important thing about using these is to note how wide the temperature window or "spot" is for the distance you are measuring from. This is usually shown on a label having a conical graphic showing the spot diameter at various distances from the surface. Take a temp reading of the header from too far away and you will likely also be taking into account the block temp surrounding it.
They are a great, economical diagnostic tool to have and alot safer than using your hand to feel temps. Highly recommended. Good luck on your project!
