As far as the warm end of the temperature spectrum goes, I have used a Crockpot without the crock and put a thermometer probe inside. when I wanted it to stay at a specific temperature I threw a blanket over it and shut it off. I suspect you could get it to hold temperature better by simply controlling the voltage to it. For the cold end perhaps, you could put the ceramic crock in the freezer (roughly 0°F). It would warm slowly enough that you could perform testing along the way.
