Calibration Weight Selection Guide

This calibration weight selection calculator helps you choose the correct calibration weight size and OIML accuracy class for your weighing scale. It is useful for laboratory balances, jewellery scales, industrial platform scales and commercial weighing machines.

How Calibration Weight Is Selected

Calibration weight is normally selected between 50% and 100% of weighing scale capacity. The required accuracy class depends on scale readability and application type such as analytical laboratory weighing or industrial platform weighing.
