I think my thing is too short

Ok I have two problems with my temp controller

One is I lost the instructions. DOH does anyone know how to change it to Fahrenheit

and the temp probe looks like it is undeveloped LOL will it work in a RIMS tube or should I buy a new one. And if so what?

Rex-C100 does not support Fahrenheit. Not sure what kind of temp probe that is. I dont have any experience with the Rex C100 but I haven't heard good things. If you want another budget controller that works well then ebay Mypin TD4 and PT100 RTD probe.

That looks like a k-type thermocouple. I'd recommend upgrading to a PT100 RTD. If you're okay with celsius, that controller should be okay. If you want to upgrade, I'd spend the $24 on a TA4.
