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?

Cheers!

Steve


How about trace heating cable?

You will need a dimmer (at the very least) to adjust the temperature.

You will need some kind of PID temperature controller to maintain
closed-loop feedback of the temperature.
