Is there a significant difference between using a sling psychrometer and a
stable psychrometer.  I have never really head the term "stable"
psychrometer, does this simply mean a digital version?  When calibrating a
hygrothermo graph, should the wet/dry bulb reading be taken at a certain
time of day?  Can anyone suggest an affordable source of stable
psychrometers?  Thanks
