Acogedor 10Mg-100G Calibration Weight Gram, Precision Calibration, Test Jewelry Scale, Laborary

Great product

I purchased these calibration weights to ensure the accuracy of my scales. These weights arrived well-calibrated themselves, and when I used them to check the accuracy of my scales, they consistently registered the correct weight. This leads me to conclude that they have been accurately calibrated. Overall, I'm very satisfied with this product as it serves its purpose perfectly. I highly recommend it for anyone who needs to calibrate their scales.

Weights were accurate for all but the most exacting work, most to the second decimal. Smallest weights had most variance.

Best product with accuracy

These were not as accurate as I was hoping, but a decent value. So I will keep them. The smaller weights are small rectangles of sheet metal with a bent corner. It comes with a very cheap pair of tweezers that works OK but not great. The small rectangular weights are not well labeled, perhaps not at all. My eyes aren’t what they used to be, but I am wearing reading glasses.
