Hello,

Suppose if I were to measure outside surface pipe temperatures with a contact thermocouple (wrapped in duct tape or something), how accurate would this be in a 1/4" copper pipe? I'm trying to save some time for my degree project and was wondering if this is a viable option.

If not, does anyone have an idea how to get a thermocouple inside of a pipe cheaply? I was originally going to use these special NPT pipe thermocouples but they were too expensive

Regards,

Patrick
