I am considering buying a cheap (that is essential!) scale capable of measuring tiny weights - up to 10 grams would be sufficient.

I probably don't really need true milligram accuracy or sensitivity but the common next step, 0.01g, is a touch too coarse.

Has anyone got bought one and found it to work as advertised?

ask a drug dealer

Ah so you don't want a stylus pressure gauge then. The Shure one was very
crude and consisted of a pivoted arm with a mirror showing its position
against a scale, and a sliding weight also with a scale on that part of the
arm. The idea was to put your picup on one end, adjust the weight by
sliding until the mark in the mirror was on the centre, and read off the
weight on the scale where the sliding weight was. Just don't breath while
doing it.. grin.

The leader in this field of weighing mass to that level of precision and
accuracy would be Sartorius

So Ebay might be a good source?

Oh yes....

I have a 500g fullscale 0.01g resolution scale, ten-twenty-off-ebay quality.
Checked with weights that were calibrated a few decades ago: good enough!
Linearity, reproducibilty, etc. all within a few least significant digits.

There are many, many, similar scales with 0.001g resolution on the Bay. Some
come with one or two weights, for calibration -- go for it. And perhaps an
apothecary/lab tech/pharmacist/drug dealer could check the calibration weights
on a scale that is known to be accurate...

Interesting - but rather missed my insistence on "cheap"! I have been looking at the ones from about £6 upwards on ebay, aliexpress, etc. My need is not sufficient to pay out over £40 let alone hundreds. Nice machines though they might be.

Yes - it was the huge number that made me ask!

Good that at least some are decent enough. Thanks.

I went with one that I liked the look of, also not the very cheapest, but maybe
double the lowest price. Still close to nothing...

The scales including postage cost less than a single certified accurate weight
1g stainless +/-0,1 mg F1 class: 22‚¬ plus postage. A 1g class M3 weight (+/- 10
mg) is 3,30‚¬...

I'd go for cheap scales and one or two weights, or more, depending on your
accuracy and linearity requirements, borrowed or bought, and from a reputable
source.

Indeed.

Maybe someone in alt.drugs knows of a good balance :-)

The ones with the sliding glass doors on the side,
help keep air currents in the room, from wiggling the pan.
This is an example of what I'm thinking of.

https://www.amazon.ca/0-0001g-Analyt.../dp/B0146C4RRO

(I used to work in a government chem lab. Many fancy digital
lab instruments -- but the milligram balance was an old
mechanical one, very nice. The fine tune is a gold chain
on a reel. And the pan won't settle down, unless the
glass doors are closed.)

If I bought an instrument based on strain gauges, I'd
buy a set of calibration weights for it too. If it was
an old pan balance, then using calibrated weights is
part of normal operating procedure. (Calibrated weights and
tweezers to load/unload.)

I can't find pictures of our old milligram balance, but
this is generally a problem with labs anyway. Very
few pictures to show you what typical setups look like.

If I bought the sample Amazon item above, I'm sure the plod would
be sitting in a car out in front of the house :-)

A 20p piece is 5g. Obviously new and clean. Other coins are available.

I have half a dozen similar scales. My favourite is

https://www.amazon.co.uk/gp/product/B01N323E64/

It has good repeatability, max weight (which you don't need) and settles on a
reading quickly. You would have to decide about convenience as it has an odd
lift-off lid.

These cheap and cheerful scales clearly have limitations regarding accuracy
but the value for money is astounding.

I'm tempted to ask why you need to weigh such small quantities. If
you're weighing something soluble that will eventually be used as a
solution, weigh out one gram, dissolve in 1 litre, and then every ml
of solution contains 1 mg.

Or there is this https://tinyurl.com/y5mgovbr on Amazon, which has
received a lot of good reviews, although I wouldn't trust a 50g weight
as a calibration standard - 50mg perhaps, or even 1g, but not 50g!

I have something similar. I don't need milligram accuracy but I
sometimes measure small quantities of salt & winemaking ingredients &
my normal kitchen scale only has 2 g resolution (& I assume it has
poor relative accuracy close to zero).

polygonum_on_google has brought this to us :

I bought a 0.01g digital for weighing out when thinking to make up
e-liquids, along with a set of clibration weights. I was on the nose
all the way through, but didn't cost a lot - just one month wait from
China.

I've found those cheap milligram Chinese balances badged 'Diamond' you
get on Ebay are surprisingly good. If you want absolute accuracy (say
you need to weigh out exactly 5mg of something, then possibly not) but
they will certainly consistently discriminate between two samples when
one is only 1 or 2mg heavier/lighter than the other. For under 15 quid
you really can't complain!

I think you'll find your requirement for greater accuracy than Chinese drug dealer scales is going to prove expensive. The latter are of course less accurate than their displays suggest, but certainly cheap.

Could try scales used for weighing gunpowder for reloading bullets
