Review on 🔩 Stainless Steel Calibration Weight by Goetland by Michael Hudson

You won't believe the accuracy of this thing. I am an analyzer in a lab and have this for my personal use. I wanted to test their accuracy and it's amazing. I tested them on a microbalance (1/100,000 gram) and most larger scales (1 to 20g) were within a few hundred thousandths of a gram. I believe 20g weighed up to 20.0002. It's literally 2 micrograms. A VERY small piece of dust can cause this type of scattering. Smaller weights, in the mg range, turned out to be even more of a percentage, but that's to be expected with things this small. However, 1 mg was shown as 1.992 mg, just a few micrograms. Amazing Accuracy.
