Depending how much money you want to spend, you can also get pt10k
and even pt100k RTD's, to satisfy particular needs for resolution,
self-heating, inductance, mass and the many and varied noises.
And if course, we cannot talk PT100 and fail to repeat the old pun:
"PT100 is the gold standard for temperature measurement"

Never attribute to malice what can adequately be explained by incompetence.
