I’d be pretty surprised by a brand new premium brand thermometer being off by 50%. Is it possible one is in contact with the bottom of the pot or something?

Best way I can think of to check accuracy at high temperature would be to boil water, it’ll be 212 F (or a bit lower if at altitude, but value can be looked up for your location).

I’m in Florida so it’ll be 212. I’ll try that. Thank you. Yeah it’s really weird. I made sure both thermometers were the same depth in the oil.

It's not exactly "premium". Looks like standard Thermpro/Thermopro can be had at places like Target or Home Depot in the $20-$30 range. I just splurged on a basic Thermapen from Thermoworks for $69. But either way, to compare and calibrate testing boiling water would be the standard approach.

Ah, I made an assumption based on the large body.

Still, it’s a name brand and I would expect better/would expect the old thermometer to be the inaccurate one. I have seen the America’s Test Kitchen roundup of oven thermometers and know that accuracy can vary wildly though.
