Very accurate!

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…

Pros
  • Calibration weights
Cons
  • I'll add later

Excellent quality!

Weights are made of high quality stainless steel with a mirror finish. A very weak attraction to a strong magnet confirms this. I only have a very old but well-preserved Mettler H10 analytical balance with an accuracy of 0.1 milligrams. I cannot use this scale to check the accuracy of the scale, but I can use the scale to compare weights. Scales (when used correctly) are extremely sensitive to the smallest changes in weight. Example 5 grams compared to combined weights of 1, 2 and 2 grams…

Pros
  • Test, measure and inspect
Cons
  • Available in black only

You get E2 accuracy at the price of F1!

The weights appear to be high quality and accurate. I weighed them to the nearest 0.1 mg on an OHAUS analytical balance. Before testing these weights, I calibrated my scale using ANSI Class 1 weights. Everything on my scale was absolutely accurate up to 5 g. 10 g weight decreased by 0.1-0.2 mg, 20 g weight decreased by about 0.2 mg, 50 g weight decreased by 0.4 mg. These are definitely F1 weights with anything up to 5g closer to E1 class so these are good weights for the money. They can be used

Pros
  • Industrial & Scientific
Cons
  • Requires a base
