وزنه های گرمی برای کالیبره کردن ترازوهای دیجیتال.وزنه های 5گرمی،10گرمی،20گرمی و50 گرمی

Very precise weights. I ordered them to calibrate a small scale but before to do that, I checked them on a chemistery scale (precise up to 0.001 / 0.0001 g). And it's juste amazing how these are precise. Just check by your self on the little table I made with the results. I differentiated 20 g weights by adding color.

Pesi campione per verificare se le vostre bilance pesano giusto. ottima qualità invio nei tempi giusti. Bene +++++++++++++++++++++

nice little weight set. don’t have a calibration checker but these will work for my needs.

Хороший набор гирек для калибровки весов

material de excelente qualidade.

nice box, weights seem good with my old scale. not the new one. (500g 0.01g LCD Electronic Digital Mini Pocket Scale ) this is a good buy
