George,

Care to expand on that? How will having a humidity gauge help him
"calibrate" his moisture meter. The moisture meter is essentially a
megohm meter that is based on resistive readings, not on ambient or
relative humidity. I may not have enumerated my response very well but
yours doesn't make a lot of sense for calibrating a moisture meter.

Made one with an old Telco "megger" years ago, calibrated it against the
meters at the college.

Think about it. With constant or nearly constant humidity, he should read
the EMC for that RH. Differences between species would be "corrections" to
the meter.
