You want a digital scale for What??

NivagSwerdna:
I have one of these and use it for measuring panacur for tortoise de-worming... I'm surprised everyone doesn't have one.
themadhippy:
Ive got a set similar  to those for measuring white powder,and a freezer full of green leaf material.But  having brewing salts and hops in the uk isn't  illegal
BravoV:
For what ?

Clearly ... obviously .. for you to spam general chat area.  :-DD
SiliconWizard:
Well, I don't know, this one seems very small indeed. But I do have a small (but still larger than this) precision scale that can take up to 2 kg, and it's handy in your lab - when you need to accurately weigh components/boards with better than 1 g accuracy.

100 g max seems pretty low, but it could still find uses in your lab, for weighing electronic components, (small) boards, chemicals when you need to make accurate mixes, etc.

Oh boy was I delighted when I could buy Chinese precision scales in, uhm, 2008 I think? Dealextreme was a fairly new thing, then I found out about Ebay selling this Chinese crap. (Crap being used in positive meaning, this is.)

I got a 0.01g resolution, max 300g scale first, then a 0.1g resolution, 2000g one, and finally, a 0.001g 20g thing. All below $10 IIRC, and they all came with calibration weighs. None of them are as good as $1000 scales with similar specifications, but no ones expecting that. The bang-for-buck is great.

Even the first one still works, after over 10 years of almost daily use. I check the calibration every few years. These seem to be repeatable, I would even dare to suggest accurate, to about +/- 3 least significant digits and have a minimum measurable offset of about 7-10 least significant digits.

What for?

Yes, I did some chemistry as a hobby and later professionally as well. Was developing films and built a motion picture film processing lab. Of course, for the short while as a professional motion lab, I mostly used prepackaged Kodak kit chemistry but I still mixed some solutions like black & white developers or experimental processing solutions from scratch. I also experimented doing the film itself, this is, black&white emulsions from scratch, using food grade gelatine, silver nitrate made from dissolving silver into nitric acid (beware: deadly gasses emerge!), bromide and iodine salts and some other special sensitizing agents I already forgot about. The combo of science + art of growing the microscopic silver halide crystals through careful process control (temperatures, stirring, chemical injection rates), affecting the film's sensitivity, graininess and resolution, was indeed interesting. A strange mix of very low and high tech, when you can produce a 100-megapixel equivalent image by a process consisting of only mixing basic chemicals. This is how it worked for well over 100 years - and of course, it still works.

Now I mostly use the scales for weighing coffee. 24 grams per 0.5 liter of water, oh yes.
