Hello all,

What may seem to be a naive question, but here goes;

I am busy installing heat tape under tubs in a rack I am building. Being that I am new to all this, I am running a set of trials on the heat tape including a max temp trial to see what happens if the t-stat were to fail etc...

One of the things that is not specified in the documentation I have referenced thus far is where exactly to measure the temperature on the warm side of the tub.

Should I measure the AIR temperature above the heat tape (say 2-3 inches above the "floor" of the tub or should I measure the temperature of the Surface with which my python(s) will be in contact?

Thanks in advance for any guidance.

Best Regards

Richard
