FYI. I don't think there's anything special about that OEM device. You should be able to replace it with any off-the-shelf k-type thermocouple thermometer and get the same results.What kind of probe do you have? The OEM one is just a 9V battery only. No option for wall wart.
I'm currently using a custom setup with a thermocouple amplifier hooked-up to a raspberry pi. It's mostly held together with spit and duct tape right now while I'm writing software for it.
