You want a digital scale for What??

Bud:
Learn what this youtuber used his precision scale for. Though the scale is optomechanical, not digital, but it is a quite elaborate device The way he sourced the test materials for the experiment may make you throw up though :o

I use the balance for cooking, weighing adhesive and such, but also to weigh out my Muesli each morning.  I started doing that after the Muesli makers reduced the amount they put in a box. Now when they do that, I reduce the amount I eat (and buy) proportionally. Tit for tat.

The Muesli that I buy, is sold by weight, not volume - so weighing it wouldn't help me! :D

HighVoltage:
One other applications for precision scales I had over the years was to certify magnets
I had a magnetic disc above the magnet on the scale and measured the difference in weight.
The disk height can be adjusted by a micrometer.

For this I used a precision scale from Bosch



Circlotron:
Useful for weighing several tens of grams of mass to add to a loudspeaker to measure Thiele and Small parameters.

My spreadsheet for calculating such:

O.P. here...
To various posters/replies, yea I doubt the ones I first mentioned would really be that accurate, but who knows!  ;D
My main point was that being the size/look of a Car Remote on a keyring, indicated the 'intended' market, haha...   8)
Mind you, I'm glad to hear from others that there are so many other real & practical uses for a need for small measurements!!
Actually, I just had flash-backs to High-School Chemistry, (nearly 50 years ago!), when we had to weigh the resultant components after
certain reactions/combustions, as a 'proof' of the calculated atomic results. No such accurate digital 'scales' back then!!   :)
