QP Calibration Weights 1000g, 8PCS OIML Class M1 High Precision Scale Calibration Weight Set, 10g 20g 50g 100g 200g 500g Calibration Weight with Tweezers for Digital Scale, Gram Scale, Lab Scale

Good set of weights for the pricepointFor our needs, these are plenty accurate, and come with a set of plastic tongs shaped to manipulate the smaller sizes.The only weakpoint I can think of is probably the case. When closed it is possible for the smaller weights to come out of their positions. We will be printing a case to replace it on the Prusa, as well as positions for a couple larger ones to complete a 5Kg set. WIll definately use the same brand of weights.

It’s 200g within error bars

It weighs exactly 20 grams.

200 gm weight for calibration. It was exactly what I needed, nice quality, A good value

True to its word

I used these weights to calibrate my kitchen scale and it worked as expected. The smell, fresh out of the packaging though... leaves much to be desired so I would advise taking all of the weights out and leaving them outside in the sun for a full day (along with propping open the case) to let the odor fully dissipate.

This weight is precisely 200grams and is mainly used for calibration of digital scales and does an excellent job

Certainly a winner
