6Pcs 4 Sizes 5g 10g 20g 50g Grams Precision Electronic Balance Scale Calibration Scale Weight with Tweezers for Jewellery Scale and Digital Balance Scale Laboratory and Other Scales

I use it to calibrate my kitchen scale

We have a laboratory grade scale that was just professionally calibrated. I bought these weights to check our scale between calibrations. They are close, but not completely accurate. The 50g weight comes in at 49.991, the 20g weights are at 20.004 and 20.007, 10g is at 9.998, and the 5g weighs in at 4.998. However, if I put the 50g, both 20g weights, and the 10g, it does come out to 100.000.
