F1 grade 1mg-500g stainless steel scale calibraiton weights kit sets, balance weights. Total 24pcs weights, use 304 stainless steel. Packed in aluminium alloy case, with factory’s certificate.

Package included:

1x 1mg weights,            2x 2mg weights

1x 5mg weights,            1x 10mg weights

2x 20mg weights,          1x 50mg weights

1x 50g weights,               1x 100g weights

2x 200g weights,             1x 500g weights

1x  tweezer,                       1x aluminium alloy case

1x certificate of calibration (see following samples, as each set is different, the error of each weights is with small difference, but the error is within the maximum perssible errors of F1 weights ).

What's the difference between our F1 and M1 Weights:

1. F1 are more precise than M1, with smaller permission error, F1 applied to the calibration accuracy of 0.01g-0.001g precision balance scales

2. F1 use 304 stainless steel, M1 use 2cr13 stainless steel

3. M1 are with adjust bar (at the bottom of the weights), F1 are without.
