Those controllers will work nicely and you most likely won't find what your looking for in 1 controller. If you do, expect it to cost thousands!
I have a few of those 1/16th DIN controlers in use too, on my powder coat oven's etc. They work great.
One thing you could do is run the main temp, through the "meat temp" controllers second alarm output. In a N/C setup, so the main controller control's heat, but if the meat get's to the second alarm level, the alarm controller interrupts the main heat control circuit
