Hi all, I need to heat a steel rod 12inches long and half and inch in
diameter up to around 40 degrees centigrade and keep it within 2degrees.
It
will need to be kept constantly at this temperature. it can only be
heated
at one end, the other end needs to be un cluttered.

Any suggestions how I can do this?

Besides all the comments here about how to go about this, it might be an
idea to say what you are using this for - someone might have an easy
suggestion for you to achieve your aim.

Cheers!
