Calibration Weight 1g 2g 5g 10g 20g Calibration Gram Scale Weight Set for Digital Scale Balance,Small Weights for Crafts, 1 Piece Calibration Weight Tweezer

Recently purchased these to calibrate my reloading scales. I checked to see if the values were correct on each weight. All weights were precise except the 1gr was .98gr. Otherwise, I highly recommend them, and you won’t beat the price for such a nice and complete set.

Good kit. Does the job.

Accurate desciption

Overall, a very good set. All weights were spot-on except for one of the 2gr being slightly heavier. A quick light filing of the bottom trued it right up. Done deal.

These are very reasonably priced calibration weights. Even so I was expecting a bit better finish even though tho goal is precise weight rather than looking fancy. Precision finish is a sign of quality control and can help keep the weights from getting dirty or corroded to keep them accurate.These were listed as being chrome plated steel, which seemed like a bit of an odd choice since they would likely have to be machined to exact weight, and the chrome plating would be compromised. Well, as you can see, they drill a hole in the bottom and fill it with what appears to lead to get the exact weight rather than machining, but you can see the chrome plating flaking off. Dunno if it is really lead, but it it is I'm kind of annoyed since I don't want lead anywhere near the scales I'm checking.Overall, these will probably do, but the poor finish doesn't inspire trust in their precision. I don't have a set o of traceable weights to check them with so I'm not really sure what I'll do with these.

I like the accuracy of the weights, the excellent storage case, and the tweezers for handling weights without transferring skin oil. I’m very happy with this purchase that allows me to validate the accuracy of my scale and to store the weights.

I really like the little case the weights are in -- doesn't take much space to store and keeps them very accessible. I checked the weights on my new SearchPean scale -- readings on the scale were exactly the same as the weights. I also checked the weights on my older kitchen digital scale -- all checked 1 gram short. The 1 gram weight on the scale showed 0. As a result of my unscientific testing l feel the weights are exactly as marked.

I loved the compact container that held everything that I needed to calibrate my digital scale. I utilized it immediately and it worked perfectly. Excellent value for the money! There was nothing that I didn’t like it would want changed.
