High Precision Scale recommendation

My Gem 20 scales are not working. I’ve replaced several and the weights are running off by more than 5%. Anyone else with issues?

Looking for a high grade precision scale, even if it is pricier.

Best,

Most people have good success with those little Gems.  We actually use one at the testing lab and it's generally no worse than +/- 3mg.  I'm sorry that hasn't been your experience.  5% error might not be all that large depending on the weight involved.  Most pharmaceuticals are only made to 5 or 10% tolerance, so if you're only introducing 5% error with your current scale, you're no worse than the professionals.

However, if you want higher precision, it's certainly available.  There are many decent milligram balances in the $200-$400 range on eBay and Amazon.

Thanks. I’ve had several stop working with measurements of a .5mg scale weighing anywhere from .169-.180. And then the weight itself (which is supposed to weigh 10) weighing 10.5-8.5.  Some scales I get readings of USd all of a sudden. I’ve gone through 4 scales in past 4 months and it’s causing up and down dosing.

I’ve been weighing with these for several years,with no problems. Wondering if there is something happening that could be damaging them?

I’m having trouble with mine. I think I have the amount- which is small, about .018- weighed, then I reweigh it and it’s.022 or .012. Today I weighed a bunch of the whole pills, which in the past has been very close to .170, and found variations between.162-.185.

I realize that there are small variations between individual pill weights, but now I can’t tell if it’s the pills or the scale.

Just replaced the batteries and my husband recalibrated it following a YouTube video. 

I ended up weighing what I thought was the right amount, after fiddling with this for 40 minutes, then adding 2 tablets that were each about .169.  Weighed the whole pile together and am thinking maybe I should be doing that from now on.
