In another thread we were talking about the trials of using regular kitchen scales when trying to get an accurate specific gravity measurement on hones.
The problem is, proper scientific scales with a reading range as broad as we need it are bloody expensive.
I've been looking at coffee scales as a possibly more accurate alternative. The ones I've been seeing have a range of 0.1g-3kg, which should be fine. And coffee beans are light, so you would think scales designed for that purpose are accurate, but are they? Would they be better than equivalently priced kitchen scales, which, at least on the ones I have at home, might vary 2g from one day to the next. I could live with that on a big stone, but 2g error when the stone is only 100g makes the result pretty useless.
Does anyone have a recommendation or ideas before I pull the trigger on something?
