The TC I use is a type K with a SS sheath. They can be purchased from http://www.omega.com/ I have mine hooked up to a PID controller from http://auberins.com/index.php?main_page=index&cPath=1 Placement in the forge is kind of your decision. If the forge is evenly heated it makes little difference. Put it in an out of the way location so you do not hit it when putting the material in or taking it out.

There are different types of TC's, depending on your need. Inside a forge you will want to put your thermocouple inside a thermowell, both to protect it and give you a more consistent readout. Thermocouples read at there tip, not along their length.
The tech dept at Omega is good about working with you.

For our application, Type K is the best suited, and most economical. (Type R and S have a combination of platinum/platinum rhodium that is very, very expensive and have a range of 0 to 3100 degF.)
Most multimeters cannot read T/C inputs. Only certain digital multimeters have the option of a thermocouple input. Thermouples have an output of microvolts (millionths of a volt).
A relatively inexpensive controller can be had at the websites mentioned in the above posts and that is probably your best bet.

This is the thermocouple you want
http://auberins.com/index.php?main_page=product_info&cPath=3&products_id=39
This is the pid if you want simple and to just read temp. It can also control a SSR if you wanted to contro electricity for a oven or say a valve for fuel supply.

To read temp you would just connect 110v to the pid and the thermocouple to the pid. The pid comes with directions. If you used the sample wireing diagram and never hooked in a SSR as it shows you would be reading temps as soon as you plugged it in. Would't even have to program. It comes programed for type K. Get it and I will walk you thru on the phone if nessecary. I have two of them and unlimited long distance.
