All the low-cost temperature controllers I've had (Inkbird, MyPIN & CXTG) are defaulted to input Type K. The most common type K in this temperature range has a -100° to 1250°C. These are the eBay/Amazon $10 ones. I have learned to keep a spare handy. The high temperatures oxidize the probe's stainless shell over time. Or you can get a ceramic holder which prolongs the life of the probe.
