DiFluid lets you visually analyse and identify the micron size of coffee grinds, using it's app, your smartphone camera, and a printable disk. And they offer it more or less free of charge (you can download and use the app at no charge, but you really should also buy their scale).
Do you KNOW the work I go through now with a Kruve sifter to check grind sizes for our reviews? It is wasteful, it takes forever, and it isn't terribly accurate either. This cannot be any less accurate, and it's WAY easier.
