The NTC is no problem. It comes with the original oven, and I measured the curves to translate the R-value towards °C.
What are the resistance values over the range desired? Will you use it for non lead solder, and will it (oven) be quick enough to heat up so as not to over stress the components?
I use a Cuisinart digital convection oven, and it is a little on the slow side to hit 225c. No problems though, other than pizza tasting a little metallic.
