humidity sensor

[Steven Clayton <smclayto@npl.uiuc.edu>]

Dear Bernhard,

regarding your Run10 elog post about converting dew point
to concentration: isn't it a matter of calibration?  At
some point the sensor must have been calibrated, perhaps
with a block of ice at some temperature.  If the sensor
manual gives the conversion of mA --> dew point, then
they must have picked an equation to go from the calibration
condition (block of ice at temperature T) to dew point.
Can we find out more about how the calibration was done?
