I have six 10 year old recording hygrothermographs - the kind with hair
bundles and a wind-up clock mechanism - forgot to bring the brandname
home.  Although I've recalibrated them using a datalogger running in
"real-time,"  I'm looking for a company that will do it properly,
replacing the hair bundles if necessary.  My predecessor sent one or two
to California at great cost; I'm hoping for someplace on the east coast of
USA.  The guilt of not using them is getting overwhelming, but in their
present state it would be a waste of time.
Thanks.
