Ah, okay. You can create the desired humidity with the salts in an airtight
container along with the sensor. Refer to ASTM 104 E (? I think) for the
exact techniques (textbooks should have it too).  Really accurate RH meters
are not that common, and of course they would have to be recalibrated
periodically as well.
