M1 Calibrated Weights (Iron)

A selection of painted cast iron weights ranging from 100g to 25kg. These weights are calibrated to M1 tolerances and are ideal test weights for calibrating and testing scales used in commercial applications. Tolerances for each weight value are shown on the individual weight page and are available with calibration certificates. Ideally these weights should be recalibrated annually. If required sets of test weights can be ordered with a custom made aluminium case to protect them.
