PID questions

[StirCrazy]

Ok for all you guys out there that play with PIDs I have a couple questions. I am looking for one that can accept the input from two different K probes.

I want one input to be used for measuring temp and switching on/off an element to maintain this temp. the other probe input is used to measure a different temp and then make changes to the first one.

so lets use a oven as an example.. I want the one probe to measue the oven temp and then maintain that temp. I want the other probe to measure the temp of the roast in the oven and then be able to set off an alarm when a preset is reached (would be nice if I could program more than one preset) and also the ability to change the oven temp set point if another condition is reached.

another nice feature would be able to control the first probe so that I could say hold at one temp for two hours then raise the temp 10 degrees every hour.

anyways if some one knows how I can do this for an afordable price let me know..

Thanks
Steve
