Since you value the instrument you paid good money for, why not lash out and
buy a sling psychrometer? You can buy one for about $50. Mine cost about $75
and came with a slide rule to determine (accurately) the ambient relative humidity.
In my shop I have, on the wall, a cheapie hygrometer which I check against
the psychrometer from time to time. You can twiddle the thingy on the back
to align the current reading with reality. My finding is that it's not very
accurate, especially at the upper end, but it's quite stable, so I have a pretty
good idea of how bad things are (especially in the depths of winter). An approximeti
on is quite sufficient to let you know when to hit the panic button!!
