with aluminum the easiest way to handle the temp is to be ready to pour the mold within about 3 minutes of the last piece of solid turning liquid, also have on hand some clean dry small bits to help cool the pot off if you think its too hot.
if you have a tig welder you can take a hunk of 16 gauge K type thermal couple with and weld the ends together to make a probe, that's all the probes are anyway. incase it in a piece of carbon gouging rod to stop the aluminum from eating it up, you can plug this into a multimeter that will read millivolts and then download a chart from the internet to convert the millivolt reading to temperature.
