DSR Precision scale 500gr / 0.01gr incl. Battery
To add precise amount of supplements i advise to use a Precision Scale.
to weight 10gram you need at least a scale which can measure 0,1grams steps (1% deviation)
to weight 1 gram you need at least a scale which can measure 0.01gams steps (1% deviation)
it is also convenient to have a scale which can measure as high as 300gram
i have found and tested this model (picture below) and found it very suitable for this purpose.
it includes an auto shutoff function
it can best be ordered together with the DSR supplements.
