how to not melt a temp probe?

You are probably better getting the Omega meter. The Fluke thermocouple addapter module costs almost as much as the Omega meter. The Omega meter has a wider range too. Most of the places that I have worked have bought their temperature measuring equipment from Omega.

It is a good idea to have an extra probe on hand. When a probe goes bad, it can give readings that are obviously wrong but it can also give readings that are off by just enough to screw you up. We have had instances at work where a bad probe caused us to spend days of extra effort for nothing.

Something that I have not seen mentioned on the Omega website is that you have to make sure that the thermocouple wires do not touch any electrically live parts like the oven elements. Aside from any safety issues (electrocution), it will often cause the meter to give wierd readings (ie. the meter reading is a varying negative value when you know that it is hot). You will know this is happening if the readings become reasonable and stable as soon as the power to the oven is turned off.

Piece of advice learned the expensive way: if you call Omega and need advice, ask for an "applications" or "technical" engineer. The people who call themselves engineers in the sales area don't know their a$$ from a hole in the ground.

I just drilled a hole in the side of my forge last night to put the 1/4-inch probe in:

Thanks for all the help on this guys.
I got some shop time last night,I ended up putting the wire in a stainless tube and stuck it in along side the burner. the meter was reading up to 2300 and holding stable so its not a range issue. After talking with mete i just wanted to make sure where my temp is for HT.I over heated some 0-1 and had some ugly grain growth issues part of the learning process i guess.
