As for this probe, have you tried it in boiling water? It might be a conicidence that its reading close to ambient-ish temperatures in K mode and it is a pt100.
Thank you both for your help, I plan on running a few more tears with the them as they are. If the reading stays x degrees warmer consistently I will adjust my calculations temporarily but then also purchase some better sensors, or at least a 3 wire Pt100
@augiedoggy where did you find them for $6? I could only find bare k type for that cheap, and I've read there are issues extending the leads with xlr cables like my my setup
