First off, I'm still trying to figure out how to post to this list, so
this is a test post and I apologize if I haven't completely adhered to
the guidelines. I also may as well make this post practical, so I have
a question I'd really appreciate any help with. My name is Chris
Handler and I'm from
Hi Doug and List,
I also have a cheap Chinese jeweler's scale - my third one in 3 years.
They seem to last about a year before crapping out. I realize it's
not the most accurate instrument in the scientific world, but I don't
keep time using an atomic watch either. I do own some calibration

I use a multi-thousand dollar scale, you are right about the cheap scales,
have bought several for the field, they are worthless.
Wanna sell the small stuff, make the investment to do it right.

Hello Listers for those of you that dont have $1600 to spend on a scale here is
a scale that is about $250.

Now for the cheaper scales that are $20 from China, I find that they are pretty
accurate to about 6 to 8 mg and on
Yikes,
Dealers selling milligram specimens after weighing them on $20 flip open scales?
All purchases of micro-mounts are suspended until further notice...

Hi Mike and all,
I absolutely agree. I used to use a $500 digital and now
Use a $135 digital and I consider them both about as accurate
As the other ~ deduct one decimal point for absolute accuracy.
(it is likely far closer than that, but one should not proclaim
a specific weight, IE .007g
Hi All,
Actually I always thought that trying to measure something like 0.001g is
very difficult.
If you measuring such a small thing on the same kind of spring scale at the
sea level and at 500m above the sea level, the scale will show you a
different result.
Simple example:

Hi Michael,
That is +/- 0.015 of a *milligram*, not a gram, and 0.03 of a *milligram*,
not a gram.
Cheers,
Mike

Hi Sergey,
I think you want to clarify that. If you try to measure something that
weighs 0.001 grams ( 1 mg ) a

Just for fun,
If anyone asks you how much you weigh "on" the Moon, tell them 20
milligrams. At least if you are a 100 kg person (10 mg
featherwe...bessyweight for a 50 kg person), if I haven't
forgotten to square something somewhere.

Hi List,
As a non-dealer, but the ocassional passer-on-of-specimens, (normally the
ocassional SA batches or other noteables), I use an x.xx scale yet have
always quoted the weight to x.x -(.x) ...with respect to my error potential.
Quoting at least a -.x (i.e. 68.8gr instead of the scale's re
Hi all you will likely never get another shot at a Graphite slice this
large, this solid and this BEAUTIFUL! Really it is gorgeous and my
very last one for sale. The remaining mass is locked away in a
university collection and gone from our reach forever. You can see the
piece here first come first
Just to clarify a bit - there is a difference between precision and
accuracy.
If the finest division on a scale is 0.1 mg, this is an indication of the
precision of the scale - how repeatable the measurement is. You could weigh
a specimen several times on the scale and get close agreement of
The 20 milligram weight would be the weight of a 100 kg person if they
were freely floating in space at a one Earth-Moon distance from the
Moon. But, and a big but - but because the Earth is 'supporting' them
when the Moon is overhead, although the Moon would pull them and
lighten the apparent
