I am working on a project where the precise & accurate measurement of single millinewton forces has become a significant boundary. Is there a cost effective device that is able to measure such small forces?

$\begingroup$ Consider to check out the help section, specifically engineering.stackexchange.com/help/on-topic in which it notes that requests to find or recommend products is discouraged. In this case, "cost effective" also becomes a subjective type of question, heading toward opinions, also discouraged. If you can edit your question to focus on a specific engineering reference, you may be more successful. $\endgroup$– fred_dot_uCommented Jun 7 at 15:42

1$\begingroup$ Look at Cavendish's experiments with torsion wires used to measure gravity. $\endgroup$– Phil SweetCommented Jun 7 at 15:53

$\begingroup$ Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. $\endgroup$– Community BotCommented Jun 8 at 14:34

2$\begingroup$ 1 millinewton is equivalent to the weight of a toothpick (100 mg). There are plenty of milligram scales available online for $20 or less. Microgram scales start at about 10x that. $\endgroup$– Dave TweedCommented Jun 9 at 14:55
