[time-nuts] What do people use for measuring temperature?

[John Moran, Scawby Design]

Final input from me on this topic.

The surprising, to everyone, result from the research paper referenced in the eevblog -

Was that the cheapest thermistor had a drift of less than 0.5mK/year.

It is the Murata NCP15XH103D03RC and is available from Mouser for 41c. Create a cluster of these and you have your low-drift reference.
