Best Mini Pocket Scale 0.001g to buy?

JerryNoBrainers - 10-1-2021 at 13:02

Im looking for a great quality 0.001g scale
with the smallest possible scale weight/frame.

a small tiny high quality scale with the size of 10x10cm and 100g scale weight
for example.

is there anything like this available?

all quality scales seem to be a minimum of 15x20cm with 250g of weight.

This one proved very useful and reliable to me: https://www.aliexpress.com/item/33044497440.html?spm=a2g0s.9...

You cant expect those small and cheap scales to accurately measure 1mg (0.001g).
You might get an accuracy of something like 0.01-0.05g on these small pocket scales.
When choosing a scale that should accurately measure small weights you should get one decimal more, ie. if you need an accurate weight of 0.01g you buy an 0.001g scale but this is with professional scales.
If you need 0.001g you should buy a lab scale with an enclosure on top.
Something like this, not a pocket scale:

I hope i didnt made you change your mind about getting the pocket scale.
Even if the very cheap ones dont have super accuracy some of them can be surprisingly good and useful.
I have a cheap pocket scale with 2 decimals, 10mg or 0.01g display.
It has been very useful.
If i want to make an experiment on the small scale, say a total weight of 1 gram to try something out, this pocket scale is good.
Even if the weight measurements arent super precise, as long as i use same scale for all measurements the proportions are pretty correct and will work.
At least for me as a hobby experimenter the pocket scale works just fine for most things.

i got 2 scales and one i 500g 0.01g for 7$ and 50g 0.001g with calibration weight of 50g for 15$.both are pocket scale.0.01g is the one i use more.

I just received a package of calibration weights from 10mg to 100g.

All my scales give exact results with all weights alone and as a combination. Some of the weight pairs (there are two of each 1g, 10g and some other) show 2mg tolerance by my most precise scale, Homgeek TL-series.

Since it is unlikely that three different scales give consistent errors, it appears that the cheap scales can be great purchase for an amateur. On the other hand, my most used scale is my cheapest kitchen scale, that is off-brand supermarket one, which has accuracy of 1g, and it also calibrates to the spot with the weights.
