Thermisors showing wrong temperatures

[dc42]

@mendelevium, I don't think that's a thermocouple. I think it is a thermistor. Can you measure its resistance using a multimeter?

@dc42
you were absolutely right in this as the sensors were thermistors. The resistance was 118 Ohms. Thermocouples do not have any or infinity. I was really misguided. I connected everything and tested and the temperatures showing are actual off by 1-2 degrees.

My profound apologies for the din I created but I am sure I have learnt something else.
many thanks to everybody who lent a hand.
