I just changed over to Flexwatt from heat cables/pads and I too get inconsistent readings on the same piece of Flexwatt when I use my temp gun. I realize that there may be some reflection going on but I try to measure a specific spot the same way every time. I get a range of temps with up to a 10 degree difference.
I am using a shelving system for my tubs (not a closed rack) but my room has a heater and stays between 82-84 degrees. Each piece of Flexwatt is 12" and hard wired with a plug. I have a total of 12 pieces with 6 plugged in to a power strip for a total of 2 strips. Yes I too am using dimmers for each strip. (I am not debating whether dimmers are the way to go but it is what it is right now and a T-stat is in the very near future.) I am not overly concerned because in general the tape is doing what it needs to do within my set-up. I am just curious because it seems that I may not be the only one experiencing temp fluctuation within a piece of Flexwatt.
I also use 4 separate digital thermometers to measure different (separate) pieces of tape and they all are different. I could chalk it up to the Zilla gauges I am using but wonder about when I start using the T-stat. I have to have the power strips the way it is already set up. If the Flexwatt fluctuates so much within a set on the power strip, do I use the piece of tape that has the highest temp to place the temp probe?
