Complete how to: Right here.

Looks like a fairly cheap and easy to best really expensive equipment. Calibrated with a know physical standard; the triple-point of water 0.01C.

I'm guessing accuracy would depend on your multimeter.

Two questions:

Is the linearity of platinum RTD's assured by the physical properties of platinum?

If linearity can't be assured, how do you calibrate it?
