This may help.

Look at: SYL-1512A  (Or any of the others, really...)

If you want to lock a temp down and use a light bulb or similar, this is 
a pretty cheap way to go. I've used them for large soldering irons, 
reptile incubators, and temp chambers. They work great if you need to 
hold temp long to stabilize everything before a measurement. Very nice 
units for the price.

I'm sure you know this, but watch your temp gradients in the chamber.
