Electrical tape emissivity Phil 6/16/2005
Hi. Using electrical tape with a known emissivity of 0.95 is a popular method to measure temperatures of objects with unknown emissivities. I've seen values of 0.95, 0.96 and 0.97 for Scotch 33 electrical tape. Although a 1% error has very little effect (<1C) on measured temperatures below 100C, does anyone have a scientific reference to how accurate this value is or who actually measured it?
