Primary low force balance
Bildnummer 11826865
| Primary low force balance. This machine measures very small forces using electrical and dimensional analysis to establish the primary standard for forces of 10 micronewtons (millionth of a newton) or less. The balance measures from 10 micronewtons to 1 nanonewton (billionth of a newton),with a resolution of 50 piconewtons (trillionth of a newton). It produces the most accurate measurement of minute forces to date (as of 2007). Previously,these forces had been measured using the weight of their mass in a gravitational field,Masses under 1 milligram,however,are too small to be measured accurately this way,so the primary low force balance was introduced to solve this flaw.
