(Dynamometer nach Collin.)
Description: This was used extensively in schools until
electronically based equipment replaced it. It has a spring frame
which is compressed by the action of a person's hand. This causes
a gear to move two dials, thus recording the greatest pressure
exerted by the hand as well as the momentary pressure. (Expanded
