1500mg weights, 1x 1g weights. 2x 2g weights, 1x 5g weights.1x 10g weights, 2x 20g weights. 1x 50g weights, 1x 100g weights. 2x 200g weights, 1x 500g weights. (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. F1 are more precise than M1, with smaller permission error, F1 applied to the calibration accuracy of 0.01g-0.001g precision balance scales.
F1 use 304 stainless steel, M1 use 2cr13 stainless steel. M1 are with adjust bar (at the bottom of the weights), F1 are without.
