if the oven-dry sample weight will always be more than 1000 g (2.2 Ibs), the a scale that reads to 1 gram is very adequate. In general, we have found that a scale that reads to the nearest 0.1 g is what a mill needs for small samples. The range or weighing capacity of the scale needs to be adequate to hold the sample.
