Calibration Weight, 1g 2g 5g 10g 20g 50g 100g Calibration Gram Scale Weight Set for Digital Scale Balance, Small Weights for Crafts,1 Piece Calibration Weight Tweezers(Silver)

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.

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 bought these to check the calibration of my kitchen scale. They are spot on.

lego muy bien el producto, solo una observacion porque la pesa de 100g no tiene el sello de M1 en la parte superior.

Good kit. Does the job.

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.

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.

Accuracy of each weight was spot on.
