If you need to measure anything in milligrams – you will need a really precise scale. This is an extra precise scale! It can measure things up to 20-grams with a precision of 0.001-grams. The stainless steel platform is protected with a plastic cover and this scale comes with calibration weights, a tiny tray for powders or liquids, and a pair of tweezers. If milligram precision you seek, milligram precision you get!
