7 PCS Calibration Weights, Scale Weight Set 1g 2g 5g 10g 20g 50g 100g, Carbon Steel Small Weight for Digital Scale, Gram Scale Balance, Jewelry Scale (Silver)

I am a retired chemist. These are very accurate and precise. Better value than I thought. Great for home use, baking and calibration . I would suggest to others to store in a clean dry place away from all liquids like vinegar and water. They should last a good while.

These calibration weights are perfect. They are more than reasonably priced. For a set of seven, you cannot beat it. Includes a 1g, 2g, 5g, 10g, 20g, 50g and 100g calibration weights. I put them on the scale and they were dead-on accurate. Shipped in a small bubble pack and plastic zip baggie they don't take up much space. Easy to use. Very functional for calibration of any scale within the weights parameters. You can get this entire set for the price of what one would cost.

This 7-piece calibration weight set is perfect for calibrating digital jewelry scales. It includes weights ranging from 1g to 100g, providing a versatile range for precise measurements. The weights are well-made, with a smooth, corrosion-resistant finish that ensures durability. At this price point, it's a great value for anyone needing to maintain the accuracy of their scales. Whether you're working with jewelry, precious metals, or other small items, this set has you covered.

Good value and each piece clearly marked with weight. I recommend you pay a little more and get calibration weights with a little storage box to hold them in place. I just put these in a little cloth bag to keep them together. Still, they seem pretty accurate for calibrating a small scale.

Love them all. But I wish it had a case.

It worked very well for me. And it helped me check the calibration of my electronic scale. I recommend.

7 weights ranging from 100g down to 1g. Good packing they all measure correctly. Worth the purchase

I recently had an issue with a digital scale, since I use this scale to reload ammunition it is important to make sure that I conduct safety checks once in a while. Normally I will measure the powder on the digital scale and then on the manual beam scale. It's a little time consuming because I have to calibrate the manual scale and even then, I wonder about its accuracy. I had not thought about check or calibration weights before, I ordered these ones and they were all accurate for the specified weights. Although they are recorded in grams, I weighed them and recorded each one's weight in grains. Now all I have to do is place the check weights on the scale to see if it's reading correctly. It's not just about confidence in the reading, since it's measuring powder charges in ammunition it's about consistency and safety.
