Spring scales (also spring balance) are designed with a fixed spring on one end and a hook for suspending things the other. Using Hooke’s Law, these balances measure force in newtons or pounds, but are usually marked to measure mass as well. HST carries spring scales ranging from 1 N to 50 N (100 g to 5000 g) and offers tubular push/pull balances.
