I'm looking for a high temperature stick on thermometer

Something like an aquarium thermometer, only for temps from 160-210f in 10 degree increments. Anyone have any idea if something like that exists?

I have a similar product from DX and the sensor is on the end of a ~1ft wire

looks good but i wonder how hot that adhesive can take

What are you trying to do? You can get a free thermocouple by disassembling “dead” laptop batteries… Plus the cells are usually fine, meaning free 18650s… Maybe that’s not your thing…
