Test weight is really great
I needed a small test weight for my reloading powder scale to be sure it measures my powder correctly. This 1 gram weight may be tiny, but it's exactly what I needed and as it turns out, the test weight verified that my scale was indeed accurate.

I purchased the following M2 Calibration Weights for the purpose of checking my scales accuracy: 1 gram, 20 gram, 10 gram, and 5 grams. The M2 Calibration Weights are less accurate that my scales capability but provide what appears to be consistent reading. It is nice to be able to check my scales performance.
How did we do?

These people are so friendly! I have 2 scales for setting the tracking force on a phono cartridge, one digital, one mechanical. They disagree by 0.25 gm. Now I know which is true!

Great price, item weighed well within tolerances. Personally using to verify/calibrate gun powder scales. Would recommend items to others.

M2 Calilbration Weight - 1 gram
Item is excellent. Fit right into my set where this was the only weight that was missing. It isn't brass like my set, but it fit the slot perfectly and completes my scale set. A great buy and glad I found this seller on the internet. This was the only place I could find what I was looking for.

This is exactly what I was looking for. Found out my scale is off three hundreds of a gram. And now I can prove it. Thank you!
