Digital scale Calibration Weights
Calibration weights are specially designed cast iron or stainless steel weights used to calibrate weighing equipment.
Test weights are manufactured and laboratory compared to a certain degree of accuracy against a known standard.
Select the maximum weight that your scales weigh up to, to get the correct calibration weight for your scales, i.e. if your scales weigh up to a maximum of 50 grams then you would select the 50-gram weight.
