This OIML Class M2 1 gram calibration weight has an accuracy of +/- 3 milligrams (0.003 grams). Use this calibration weight alone, or combine it with more weights to accurately calibrate your digital weighing scale.
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!
The product is just what I had ordered, arrived timely and will contiue to consider purchases from oldwillknottscales
