Ohaus is a manufacturer of some of the highest quality scales. Labs, universities and yes, your average cutivator uses their products. I warn you though, when you start getting into precise measurment scales, you're going to pay a pretty penny for them.

Here's a model called "Adventurer" it has an accuracy rating of 0.001 and reads in g, kg, mg, ct, N, lb, oz, ozt, gn, dwt, mommes, mesghals, taels (3), ticals, Parts Counting.
