As an FYI, The electric steam table as they are called in the food industry, will hold food at 145. So, you can absolutely get the curds up to 124. I would run some tests with a calibrated thermometer, this way you will know what number is what temp.
Also, there is a good company out there Restaurant Depot. If you have a Fed Tax ID number you can join for free. They will have all sorts of fun toys.
