not just for a hobby, that is, man...
i am afraid its hard to get "exact" point of temprature, man, maybe u can use thermometer to get near to that point, but to be exact that point, its very hard, or maybe u can use 1kw one for that, not 10kw, but, once again, only to get near to it, not to be "exact", maybe it differs like more than 5 degree or something, just my opinion,
