Hi
Before you get too carried away, remember that the acceptance angle of a typical IR thermometer is about 5 degrees, i.e. a "spot size" about an inch in diameter when held 12 inches away. So you need to be close enough for the measuring area to only be seeing the manifold and not partly overlapping something cooler. I found this out when trying to measure the temperature of 15 mm diameter central heating pipes.
