Hair bundles for hygrothermographs

Regarding hair bundles for hygrothermographs:  Qualimetrics offers a
replacement hair bundle (catalog number 50211) for its Hi-Q model
hygrothermographs for $75.  Their address : P.O. Box 41039, Sacramento,
CA, 95841, phone (800) 824-5873.  They will probably refer you to a
regional distributor.  The one I have delt with is Scientific Sales,
P.O. Box 6725, Lawrenceville, NJ, 08648, phone (800) 788-5666.  The
'spare hairs' I have for our hygrothermographs are just strands of hair
knotted together.  I suppose these bundles would work on other models, of
you can figure out how to install them.
