Sling psychrometers

From: Elizabeth Morse <*npick*> Date: Thursday, January 28, 1993 · npick

We have discovered a sling psychrometer which is spirit filled instead
of mercury filled.  You may also order spirit filled glass thermometers
in centigrade or Fahrenheit.  Our vendor is Lab Safety Supply and I can
include prices if you would like to have them.
