Was the original measurement with an IR gun? If so they reflect off of shiny surfaces sometimes it might have been measuring the body of the rack rather than the flexwatt you pointed at.
Yea it was with an IR gun. I am going to put my probe thermometers on there and see what the temp reads and get back to you. Hopefully its not faulty
@Steve Its one long piece snaked through 4 shelves, similar to rbi racks
