Hello, I'm looking at the TC-08 for a high accuracy temperture monitoring system within an enclosure.
I'm not quite clear on what the uncertainty on the TC-08 actually is in high accuracy resolution (0.025K) mode.
According to the online spec the uncertainty in measurement is approx. 1 Kelvin at room temperature. Is this correct?

Hi Dan

The accuracy of the TC-08 is the sum of ±0.2% and ±0.5C. The first refers to the measurement and the second to the cold junction measurement. The accuracy of the sensor also needs to be taken into account.

Therefore at room temperature the accuracy would be less than 1C.

In centigrade instead of an absolute measurement?

Hi

Yes it is with reference to centigrade.
